Movement was an absolute delight; it felt clean and good to move the characters. I love how simple the take on the theme was but you executed it very well! Sound effects had that "crunch" to them and the music choice was fitting, as IcyPenguin said this would be so cool as a co-op game.
There was one slight issue where I accidentally tapped the space button right after the round ended and didn't see the instructions - luckily the gameplay was simple enough that I was able to figure it out quickly.
Oh, and right when the round was about to start an error popped up and the game ended there, not sure what might have caused it.
The little things aside though, I think you have something great! The paper aesthetics fit really well and you did some really good work on this. Goodluck for the rest of the jam!
