Interesting concept! Funny enough, my team had briefly considered a similar gameplay idea, but with a very different aesthetic lol. I definitely think it's a good way of tying the jam's theme directly to the gameplay, so good job there.
I had a bit of trouble beating the last enemy, and the game ended up crashing when I tried to play again, though I'm not sure if that was an issue on my end.
Thanks for sharing your game!
