Pretty fun game, but I can't say much on the side of originality or ethics...
Let's start here: The gameplay, which was probably the best part of this game, is EXTREMELY similar to an app on the app store that Starbucks gave away for free like 6 months ago or something. I get that it's a simple idea and convergent designs exist, but this one was a little close for my liking. There is one where you are a ball and you just go up when you tap and if you hit an obstacle you lose, and then there is another where you are this little guy in a rocket I think, and when you hold down your rocket flies. The gameplay is basically this game except in it you died right away when you hit an obstacle and that you could hold instead of tap. Now, most of the people rating this have probably never played that game so they think this was entirely your idea and are rating it accordingly.
As far as art goes, the art would have been pretty good on its own, but it wasn't nearly as good as the game this is a clone of, so it kind of leaves a bad taste in my mouth... (Also, how much of it is even yours?)
And I guess that leaves us with music and sound effects. Nowhere in your description, developer update, or patch notes (which almost no one reads anyway) are there any disclaimers about art, music, or anything else. Now, I do realize that this is a jam entry, and as such the rules are a little bit less rigid, but like, come on guys. If you didn't make the music, then just opt out of the audio category! And if you aren't going to do that, at least say somewhere what you made and what you didn't! At least 3 quarters of the people who rated you for audio did so under the impression that all of the sounds were made by you during the jam. I don't know about the background music that played during the main part, but I know for sure that your background music during the main menu/shop scene is something you just downloaded from the internet. (I know because I used the exact same music in a 30 second commercial I made for a [non-LD] game over 2 years ago: https://www.youtube.com/watch?time_continue=25&v=KTfANUbgR1E)
After this, it makes me wonder what part of this game you actually did make. The particles that are created when you die is just a Unity particle system with minor changes. Nearly all of the art in the game is a recolored version of the same steel texture--a texture which, if you didn't flat out copy like your first soundtrack, is one that you probably generated with a few clicks in Gimp of Photoshop directly following a YouTube tutorial. The fire (or whatever it was suppose to be in the steel-textured triangles) looked suspiciously good for someone who only has time to draw one real texture (if that) during the entire 3-day jam. At this rate, I honestly wouldn't be surprised if it were a built-in Unity particle system.
Anyway, you get the point. When you submit a game, people think it is yours. If it isn't, you have to tell them that it isn't, otherwise you are screwing over all of the people that did actually make a game. Preferably, tell them by opting out of the categories that you didn't participate in, but at the very least but a disclaimer when you publish your game saying what music/art you did and did not create yourself.
