Tesseract

Beam Racer by Shoalmuse 2026-10-27T00:09:11Z ♥ 0

A fun game initially, though the monster was too difficult for me to beat - at first it wasn't clear how to fight it, and then after reading the comments I still struggled to hit it with the reflected beam and never hit it more than once in any game.

After Anthropocene by NE-Aquilon 2026-10-26T23:51:06Z ♥ 1

I appreciated the Tesseract nets (I assume they were save points, but I played cautiously enough I didn't die). Was the mandelbulb supposed to be more detailed than a pink blob?

Your source code upload doesn't include the header file "LD60.h" (I'm undertaking a probably doomed attempt to build it on Linux).

Abattlacus by FunBanan 2026-10-20T21:00:28Z ♥ 1

A fun and well made game. Like some others who've commented, I'd have liked some runs to go on longer. It reminded me of Balatro in a few ways.

Mixed Signals by lloydlobo 2026-05-08T23:16:01Z ♥ 1

I like the idea, and found it fun. The original version was lacking some polish, most of which has been fixed in the updated version. Since it looks like you're still working on it, I'll give some suggestions for the updated version:

Having less time for the later levels while new dials are being introduced is a problem, particularly at the point when harmonics are introduced. This is improved a bit in the updated version, with the ability to restart a level rather than the whole game, but it still doesn't give a good opportunity to experiment - in the tutorial, there isn't any motivation to explore the variety of wave shapes that can be created with harmonics. One fix might be to give the player more time for the earlier rounds of a level (or remove the timer altogether, and just have speed affect score).

I don't think the noise slider adds much to the game - having looked at the code, if you're trying to match a signal with random noise, you're better off ignoring the noise - adding noise of your own just drives it further from the signal you're trying to match, since a random number between -1 and 1 is usually closer to 0 than it is to an independent random number.

Switch Happens by Zettelkasten 2026-05-08T00:53:37Z ♥ 1

I really liked this - it's fun to see other takes on the "trains crashing" interpretation of signals; they all end up playing fairly differently. I enjoyed the freedom of building your own tracks in this game, you made the controls work very smoothly. It's interesting that we both decided to be lenient about trains ending up at the wrong destination.

I did notice what seems to be a bug where trains crossing each other didn't count as a crash - this means that if you have dedicated lines for each direction, then it never seems to crash.

Samband by Ava Skoog 2026-05-07T20:35:23Z ♥ 1

A very good game. Given how easy it is for a Ludum dare game to be unclear about what you're supposed to do, I'm impressed you pulled it off when doing that deliberately.

Mixed Signals by Fractal 2026-05-07T18:38:50Z ♥ 2

When I saw the option to set waveform, I was disappointed that the game wouldn't involve combining waves to make a more complex waveform. I pleasantly surprised multiple waves did show up a few levels later :) . I really like the idea, and it was very well executed overall - the controls are clear, and introduced at a good pace. My one complaint is that for some challenges, it gets very hard to see the difference between the controlled wave and the target, although that does mean I then get a chance to adjust other settings in way that makes the difference clearer.

I did make it to the end.

The Homing Crows by fabonacci 2026-05-06T19:26:07Z ♥ 0

This is a great idea - orders taking time to arrive is something rarely modeled in strategy games. Being able to cut units off from receiving new orders leads to interesting gameplay, I'd like to know how a game between 2 human players goes. Here's a stalemate I managed to reach: Screenshot 2026-05-06 at 20-17-18 ldjam_59.png

It could do with clearer controls: - A highlight/circle would be more obvious than just making the selected city slightly bigger. A selected city should look noticeably different from one the mouse is hovering over. - There should be some feedback when an attempted order is valid/invalid (one way to do this would be to draw an arrow when the mouse is hovering over a valid destination). - It's not clear exactly when the animation has ended and you can start to issue the next order - it's tempting to click on the first city of the next order early, and there's usually no reason the game should prevent that. The suggestions above would make it more obvious when the first click didn't count because the previous turn hadn't ended. - It would be nice to have a bit more information on what your units have been ordered to do, e.g. count units moving through a city separately from those staying in the city. On the other hand, you could say that remembering what's happening is part of the game.

They Devour Signals by justking144 2026-05-06T16:40:29Z ♥ 0

Very fun. The difficulty curve felt right, which is something I always struggle with when I'm too familiar with a game after testing it continuously over a weekend.

VOID by Kyanoss 2026-04-30T20:28:43Z ♥ 1

Beautiful graphics and mechanics. What kind of goals/objectives for a gameplay loop did you have in mind?

Trot in the Poly-verse by spooooodermon 2026-04-30T20:18:01Z ♥ 0

Inverted mouse controls are not for me, particular in an environment where they keep sending me back to the start. I eventually got past the first level. The music and graphics were cool though.

Electrician Simulator by Akuta Zehy 2026-04-30T19:32:54Z ♥ 1

It took me a while to build it on linux (for other archlinux users, here's what I did:

```sh git clone https://github.com/AkutaZehy/electrician-simulator.git pacman -S godot-mono pacman -S godot pacman -S scons # may not be necessary curl --location 'https://downloads.godotengine.org/?version=4.6.2&flavor=stable&slug=mono_export_templates.tpz&platform=templates' -o Godot_v4.6.2-stable_mono_export_templates.tpz # ~1GB download godot-mono project.godot ``` - Then from the ui that opens, click Project->Export; - then tell it about the export templates you downloaded - and create an export option for Linux - then export it. (should create `Electrician Simulator.sh` and `Electrician Simulator.x86_64` either of which can be run to play the game)

)

This was a fun game, I really liked it once I worked out what was going on. It did take me until the end of the game to realise that clicking on the message box gave more exposition/explanation. I wouldn't have minded some harder puzzles after the test panel lets you work out what things actually do; but it's the right length for a jam game.

Mines of Enceladus by auxiliarymoose 2025-10-20T07:46:26Z ♥ 1

A very spooky game - I don't think I've seen a Ludum Dare game capture that mood so well.

Unfortunately, I couldn't vote on your game (I did submit to Compo, but usually everyone who makes a game can vote on each other). Did you tick the "opt out of ratings" checkbox?

Webbed Up! by Fractal 2025-10-19T02:43:59Z ♥ 2

This was a fun game with a very neat and well implemented core mechanic. I particularly liked how you need both speed and patience (and it's possible to trade some of one for the other). I also appreciated the leniency - if you knock into a bug while finishing off catching it, it counts as caught :). I played to level 30, which looks like it's the (repeating) end, although the difficulty didn't seem to increase much past level 19.

@fractal given your username, you might want to check my game out.

Death or Taxes by atsh 2025-10-15T05:47:05Z ♥ 1

Fun to play and I definitely appreciated the simulation. I played it a few times to work out what was going on. It appears that you can destroy tax revenues by setting VAT higher than tariffs, creating a tax loophole where people buy from the market since that's cheaper than buying from their neighbor, and reducing income tax revenues at the same time since people can never sell more than the market demand (which isn't affected by people buying things from the market?).

WebWeaver by JPGFG 2025-10-10T21:09:40Z ♥ 1

A fun and well made game. Thanks for explaining the details of the web strength mechanic in the comments, it makes for an interesting problem. I like how (what I think are) the best solutions for most levels look appealing (https://en.wikipedia.org/wiki/String_art).

Beelines by raysplaceinspace 2025-10-10T20:35:16Z ♥ 1

This was a great game. Dividing attention between the different things (the small scale questions of which order to visit flowers, and the larger questions of which regions of flowers can / should each bee visit) is tricky but fun.

It would be interesting to know what the optimal score for an average map is; I assume it's much better than anyone's achieved.

Runestone Alchemist by good.enough 2025-10-07T02:07:37Z ♥ 0

Haven't played it far yet, but the ldjam.com embed cuts off the "To stream" button which lets you get past the opening scene. The web link does work.

Petals by AppoxGames 2025-10-07T02:00:26Z ♥ 1

I enjoyed this. There's more strategy to the game than some people suggest - it needs a bit of spam clicking, but I did best by cultivating an area with lots of 5-petaled flowers to get a very long chain, spending as long as possible at lower levels to place pieces carefully without setting off the big chain. I got a score of 1069 by this method, although that took quite a few attempts.

Something that took me a while to understand: When a flower fully blooms, it doesn't boost all surrounding flowers, only those in the pattern most recently used by the player.

Inside Creatures Out: What is your gaming MBTI? by CatZP 2024-10-12T03:14:59Z ♥ 3

"You favor making efficient in-game decisions, even if it means overlooking character emotions or story elements" Now, which answer will give me the stronger build? :)

Happy Bees by Lunaria Rava 2024-10-11T03:43:06Z ♥ 1

This was a demanding puzzle. I was able to play the first 50 tiles with very hive being directly adjacent to the flowers it needed. I kept going to 180, at which point I felt it was too difficult to keep track of everything. It would have been nice if the game could expand to take up a full screen so I could see more at once.

Overall, a very good game.

Nectarmancer by shamotte 2024-10-11T00:01:05Z ♥ 2

@cliff-coffee That took me a while to figure out too - you need to direct the bee to the flower, then to the start button. The bees approximately follow your mouse. This is the main game mechanic, so they combined a tutorial and start screen. It's a fun game once you get the hang of the controls, although the end game screen could be improved (a restart button, a description of why I lost, and a final score would be nice to see).

Tiny Rescue by LilieBagage 2024-10-08T00:34:50Z ♥ 4

This brought a smile to my face :) .

Sandwich Siege by Thassar 2024-10-07T22:36:57Z ♥ 2

A neat tower defense game. The ants were almost at my sandwich by the time I figured out the controls, but I managed to build things quickly enough to save it. I struggled to figure out the upgrade menu.

If you're reading the comments to find out the controls: WASD to move around the map; click on the icons in the bottom left to select a defense, then click on the map to place it; click on a built turret to open an upgrade menu.

Cubic Showdown by Rewzu 2024-04-28T16:15:46Z ♥ 1

This was a fun game, thanks for making it.

Kitty Conjurer by Tyler Slabinski 2024-04-22T22:16:09Z ♥ 2

Nicely done. An original idea that's been well implemented.

Ascension by Gabriel Chan 2024-04-17T04:13:20Z ♥ 5

I found the game very hard at first, but after calibrating, I immediately more than doubled my top score (from ~11000 to ~22000, then quickly to ~40000 on the first level's normal mode). I suspect other people who found it hard hadn't done this.

I was suspicious that after calibrating, I seemed to be getting 'perfect's quite far from the targets, so I tried turning my headphones off, then playing with and without audio calibration and still noticed a huge difference in my result. Is it possible there's a bug which makes the game much easier when the calibration amount is non-zero?

The Ritual by silkworm_sweatshop 2024-04-17T02:02:37Z ♥ 2

Fun puzzles, took a while to get the dark goat (I tried some more complicated guesses for its recipe first). I particularly liked the sounds.

Is there a mistake in the text on page 2 of the book?

Limites Spatii by Jamtempisto 2023-10-21T00:35:35Z ♥ 1

A nice game, I like what you did with the theme, although I'd like to see a version without the colors and answers where you actually need to think about the limits. I imagine it would be difficult to have a collection of problems which were simple enough there's a chance to get them in the time they're on screen but also sufficiently varied (although "simple enough" varies substantially by player).

Diminutive Dungeon by Rose 2023-10-08T20:59:48Z ♥ 1

I liked the game, and played until I had everything. Perhaps it could have been more punishing of failures, but that might have made me give up sooner. The difficulty curve felt backwards, since things get easier as you get upgrades, maybe the things on deeper floors should do more damage?

Greatest Sandwich by Fis 2023-10-08T20:46:55Z ♥ 2

A very fun and demanding game, I really enjoyed playing it. The hitbox for putting stuff into the pans should probably extend slightly lower - in particular, there shouldn't be a spot where you can click to pick something up, but where releasing drops it.

AdTension by Everal 2023-10-08T20:08:30Z ♥ 1

After turning off an ad blocker, I had fun playing. I felt that everything being in a language which I don't know added to the experience, since the point is that this kind of website doesn't actually care about the content.

QPCA-77B by Jimbly 2023-10-08T16:26:52Z ♥ 1

This is a fun game. Very similar to TIS-100 as you say, but it's nice to play more of that :). I'm seeing what I can do about the high scores in the cycles category.

Pazuru Packing Sushi by Gabreu 2023-10-08T16:21:28Z ♥ 4

A nice puzzle game, and very on-theme. A problem I had was that it felt like things changed shape when rotated. This made it frustrating when the onigiri wouldn't rotate properly :). I now understand that's because of the perspective, but there aren't quite enough cues (e.g. shadows) to make that obvious, and it made it hard to see how things would fit.

LD54 - Box Survival by burnedkirby 2023-10-05T18:14:14Z ♥ 1

This was very fun - I like the minimalist style, even if it was just due to lack of time. It's your choice, but I'd turn on ratings if I were you - it's good to get an idea of how your own view of your game compares to what other people think of it, and if you don't rate other games, the system means you won't get shown to as many people as you would otherwise.

Space slug by Normality 2023-10-05T16:41:18Z ♥ 1

I really like the idea, but the controls were hard to get used to. The fact that walls are "sticky" means it's possible to get stuck in the tutorial level, since you can't move the printer once it has hit a wall, although that's less of a problem after the tutorial (I appreciate that physics is tricky and it's you've done a good job of not letting solid things overlap).

Too Maneon Loots by lastuck 2023-10-03T17:01:04Z ♥ 2

Very nice game. It's a bit too easy to accidentally click the quit button (which doesn't do anything useful on itch.io) when the game ends, but that's only a problem because I wanted to keep playing it.

After the very start, the details of item's stats don't seem to matter much - Once I had level 3/4 equipment, I always died to my inventory overloading, so I just tried to quickly equip whatever gear had the highest level and best border and throw stuff out as fast as possible, I think it could be improved by balancing things so that dying was more likely later into the game (I reached level 8 or 9 at best).

Animal Teleporting by JamesW 2023-10-03T10:53:53Z ♥ 3

A neat puzzle game. I particularly liked how the crab's movement rules made it feel crab like.

Robo Rush Hour by michaelaranda 2023-10-03T01:21:42Z ♥ 2

A very fun and addictive game - it felt like my skill was improving the more I played. The clock could be made more obvious to new players, it took me a while to realize it was more than decorative, and I wouldn't have minded it flashing or something to remind me when the time was low - even with a bit of practice, trains quite often left with some easy-fill spaces. The 3D graphics sometimes made it hard to quickly tell exactly which spaces were filled and how things were aligned, which caused some frustrating mistakes.

Tower Swap - A Card TD Game by Jeldrik 2023-10-02T22:57:55Z ♥ 2

A fun and nicely polished game, the UI is smooth and the tutorial/in-game help is clear. For some reason, Wave 24 never ended, although enemies stopped appearing (I got there by upgrading the explosion tower to have minimum cooldown).

Installing Engine by Kinami 2023-10-02T21:23:49Z ♥ 1

Not the most painful installation process I've been through recently, I'm sorry to say. I hope you treat a low score for fun as a sign of success :) .

Landfall by LCStark 2023-10-02T16:47:50Z ♥ 1

A nice simple colony simulation, although it took me a while to realize that I needed to click on the landing pad (the raised platform) to get any new colonists. I was expecting them to start arriving automatically once I had housing.

Lots of clicks are needed - automatic assignment to free jobs and the ability to place multiple copies of the same type of building in quick succession would make an attempt at filling the screen easier.

Moon Festival by Teto 2023-01-26T01:01:10Z ♥ 0

This could do with a slightly clearer UI - when selecting a card it's not obvious at first exactly what can be clicked on (they flash, but so do lots of other things on the screen). I was also not expecting continuous input in a card game. Once I'd figured out how to play, it was fun, and I would have liked it to last longer (with some more difficult levels).

Elite Brain Harvester Zombie by Pulni 2023-01-21T00:16:12Z ♥ 1

Fun to play, I made it to level 16 before getting trapped by the trees (which things block movement could be clearer). At first I didn't realise you could move - level 8 is the furthest I got without moving.

[EARTH-811] by Bastienre4 2023-01-20T23:48:33Z ♥ 1

I liked the idea and it was well executed - I had fun playing it. I should let you know that I ran it on Linux and the first time I clicked anywhere, it segfaulted. Upon restarting, it worked fine, and I haven't been able to reproduce it.

Bonsai Season by JuanRod707 2023-01-17T16:46:03Z ♥ 1

A very nice game, it was fun to play for a bit and I really like the idea, although some parts of the UI were awkward - 3s in the font looked like 8s and the overlapping hit-regions made it tricky to click some things. I'm glad the timer was so slow - it would be hard to learn the game properly under time pressure.

Soil and Toil by squimmy 2023-01-17T16:06:05Z ♥ 1

I liked the game, getting through the start is a fun puzzle; but once you're no longer in danger of running out of food, it becomes a bit too easy.

CardVest by RealTanHen 2023-01-16T17:46:06Z ♥ 1

A nice game. It wasn't immediately obvious how buying things worked (e.g. I didn't realize at first that using items would be permanent or that things stayed out until they were used rather than being shuffled every day). I ended up stabilizing by just planting leeks and choosing the wettest weather possible.

King of Veggies by pinchazumos 2023-01-16T16:21:05Z ♥ 1

An excellent game, I got to 178. Rules are easy to understand, yet there's substantial strategy involved.

Info harvest by island-jam-2-group-3 2023-01-16T01:14:42Z ♥ 1

Fun game - I lasted until 2:30, but it seems like it might be impossible to get far past there.

Click Click Farm by boaheck-artgent 2023-01-11T00:25:45Z ♥ 1

Nice game, the interface works well and I really like the music.

I made something like a clicker game myself (I'm surprised I haven't seen more of them) although we took it in different directions.

Dungeon of the Dragon by Ellie Rasmussen 2023-01-10T23:10:48Z ♥ 1

I liked this game - finding a balance where you kill some of the adventurers but not all of them is challenging. The reputation does seem to swing backwards and forwards since a dungeon that kills any of the strongest adventurers will kill almost all of the weaker ones. It did feel like it was hard to react to anything - when you need to place another trap, you don't have any money and there doesn't seem to be any way to remove traps when you want more adventurers to escape - this means I spent most of the time just watching and hoping that my traps would kill that last adventurer.

Catchy by danmerey 2023-01-10T20:38:08Z ♥ 1

The game was fun, I really enjoyed the sailing mechanic - racing(multiplayer or single-player) like this would be interesting. The "fishy guide" you gave in the comments should probably be in the game - without it, it wasn't easy to know what to look for. I wasn't able to catch a catfish - they might be difficult to distinguish from Cod that are fading out.

Plant to Survive by oddang 2023-01-09T20:32:12Z ♥ 1

Nice game, I managed to complete it. Clicking on plants to upgrade them felt glitchy. Is it supposed to be impossible to upgrade a plant when enemies are too close to it? If so, this should be explained.

noCharge by Temulgeh 2021-10-20T20:26:52Z ♥ 1

I pressed Alt+f4 to get the bonus level, but nothing happened. Perhaps that's a Linux(in browser) bug :) .

Nucleon Soup by Schuster 2021-10-05T15:18:37Z ♥ 1

I really like this game. Did you consider scraping Wikipedia to support larger nuclei?

Unstable Pinball by T C 2021-10-05T02:11:15Z ♥ 3

That was fun, but it took me a while to complete - I'm glad you gave us infinite lives. I didn't realize I could move the diamond until reading the comments afterwards, which made it a bit harder than it should be :) .

Sliced Ice by Void4 2021-10-05T00:10:25Z ♥ 1

A fun game, although the it crashed (window went completely black) when I circled both enemies simultaneously on level 5.

Factowery by demogorgon 2021-10-04T19:42:01Z ♥ 0

This is a fun game. It feels a lot like factorio layouts, but the lack of any way to cross paths without streams merging makes it very challenging to optimize.

Alpha Reboot by ilokimo 2021-10-03T23:52:20Z ♥ 1

I got past the first round by guessing the missing letter, but I couldn't work out how I'm supposed to use the quantum stabilizer since it's also password protected at the start and I couldn't find any clues about its password.

F=g(m1m2/d^2) by mungobulge 2020-10-05T16:03:08Z ♥ 1

Fun game, but one question: If the universe is a Klein bottle, why don't you appear to change direction of rotation when you go through the top/bottom?

The Loop by Jin9310 2020-10-05T02:57:38Z ♥ 1

I really like the game, but it seems that collision detection doesn't always work - if I go above an object it sometimes thinks I hit it, particularly if I changed direction while immediately above. I'm not sure if I missed one, but the highest score I remember is 68.

Life Alive by ClaytonRumley 2020-05-08T23:13:31Z ♥ 1

Loved it. I'd like to see how it plays out with many players at once.

Game of Life+ by Teo Miklethun 2020-05-02T00:16:44Z ♥ 1

Very well made. Some of the levels were pretty hard, I enjoyed solving them. I particularly liked the glider level. The animations for cells being born/dying were a very nice touch.

I'm using Linux, but got ``` Error: Couldn't load project data at path ".". Is the .pck file missing? If you've renamed the executable, the associated .pck file should also be renamed to match the executable's name (without the extension). ``` (repeated twice). It worked when I downloaded the source and ran the executable from inside the source folder.

Linux Simulator 2020 by smbe19 2020-04-25T00:38:01Z ♥ 0

Great game, but a very steep learning curve. I found that I didn't have time to follow the tutorial, and if I start off well, then requests increase faster than I can afford hardware. I only felt able to get the hang of it when I was stuck at 1 user.

At that point, about 24 requests were succeeding each day and 8 were timing out, but I couldn't diagnose why requests were timing out (I tried blocking various request types with iptables, and that didn't help me).

This game is broken don't play it by mcaddie 2020-04-25T00:34:45Z ♥ 0

I got it to run on Linux (needed to install pygame) and by reading the code, I realized that you need to click a blue square then a grey square (moving the blue square and making sometimes making new ones?), but couldn't work out the rules. It looks you've written an AI for green, but it runs pretty slowly (I must wait several seconds between moves).

Down to Earth by ruthiepee 2020-04-24T23:14:41Z ♥ 1

I like the idea and the feeling of shooting asteroids with coconuts, but it seems like I could keep the last flora and fauna alive forever - I got to 4000 before giving up.

Keep Gannet alive by Monish Vyas 2020-04-24T17:09:49Z ♥ 1

Simple, but surprisingly hard. It was fun to play.

One Step Darker by thijs9907 2020-04-24T01:50:38Z ♥ 0

The animations are slow, and are particularly frustrating when the character turns more than 360 degrees, but the puzzles were fun, and I like how the light fading means they get harder as you move.

Conway's Garden of Life by davidsheadgames 2020-04-23T00:54:48Z ♥ 1

Hi, I also made a game based on Conway's game of life, but took it in a different direction. I really like the way your game makes me think about GoL in ways I hadn't before - for example, are there any setups where you can live while harvesting everything which lives 3 turns? If you get to a rotating pattern of 3 cells of a 2x2, that works, but can you reach that from a single initial setup while harvesting everything as soon as possible?

Life by pke1029 2020-04-22T23:22:38Z ♥ 0

Hi, I really like this game, particularly the space battle idea.

I also made a game-of life based game, but went in a different direction (multiplayer, on a persistent world). In a sense it's dual to your game since the nominal goal is to keep your cells alive and you play by placing cells rather than removing them.

Life by esenti 2020-04-22T23:02:15Z ♥ 2

I also made a game-of-life based game, but went in a different direction.

I really like what you did here, it makes very nice use of game of life patterns.

YAB by Lars-Erik 2020-04-20T23:49:22Z ♥ 1

Took me embarrassingly long to realize there was any strategy to it, but it was fun once I did.

Don't taste the lava by mira 2020-04-20T23:42:32Z ♥ 2

Very well polished - nice animations, perfect learning curve, no bugs I could see.

I finished the last level with 3 pieces left over.

There is no plant B. by jka 2020-04-20T22:35:26Z ♥ 0

I couldn't get the linux version to work, possibly because I'm using xmonad(a tiling window manager). My screen goes black for a few seconds, then returns to normal. The program does not terminate, but gives the following console output:

Fun game. The jar file runs on Linux, but gets very slow after the first level (making it much easier, so I couldn't tell if the enemies were harder). I needed to disable my second screen to get the shooting direction correct.

Getting past "Landing..." sometimes took a while and pressing various keys helped (beware: escape quits).

Interesting mechanics, I'd like to try more levels of this. The interactions when pushing rocks are hard to discover if you think they don't exist - rock->trap destroys both; rock->anything else destroys rock.
