The game plays well and fits the theme perfectly, but I do have a few recommendations. Right now when you jump it feels like I'm constantly pulling up instead of actually jumping. Instead of doing this I recommend doing one upwards force, and increasing gravity after the player lets go of jump. Along with that I think the music is nice, but feel off when it stops/starts so abruptly on death. Besides those small things the start and end screens look very clean and overall the game is fun.
