@mika-la-grand I am going to try and hit on all of your points really quick so here we go. We did polish everything and I feel like the game was quite fun on its own, but you have to play it right. A game made in only 4 hours for a 72 hour game jam would not be very good, I participated in 5 jams total and it's always idea/basics day 1, finish mechanics day 2, then polish day 3, always seems to work really well. The teleporting isn't a game mechanic, more of just a clever way to access the shop. There are spells that help you attack bats, but you said you didn't use them, that's on you. I also assume you didn't sit through the tutorial which, while made quickly towards the end of the jam, so I admit graphics aren't great for the tutorial, it does cover a lot of things that you had trouble with.
- The Gun and bow do not have limited range, you learn how to aim over time, otherwise they are too OP. The gun can shoot infinitely far and you can pull back the bow to fire all the way across the arena. - Staying in the shop, while strategic, does not increase your score, and actually hurts you because your score is not increasing, so the shop has its time and place. - Like I said earlier, there are some really good spells that improve the game experience, so you should consider playing the game again if you did not use spells at all. - Bats fly at you and you must kill them before they hit you - You just have a bad computer. If you play on medium graphics there is no issue with the game speed. You must select a level of graphics your computer can handle, and we even said above in bold how important that is. - If you think our game isn't polished you can't also tell us to add more features. Each ground enemy has a different speed, but all are melee. - I would rather prefer a wave system in the game. There is one, it is just hidden in the code, unannounced, and can sometimes be fast. This is a change that I would make. - If you sit through the whole tutorial it give you everything you need to play the game. From your comments above, it seems you skipped the tutorial.
Your list of changes is mostly not changes, and they are not difficult to add because they are in the game. Thanks for the comment on the models. The game isn't bad, it is meant to be comical with the enemy types, and intriguing with the gameplay. If played correctly after watching through the tutorial, the game is quite fun, it has some issues, as any quick game may have, but not many.
