So, it's a little rough. Every level I tried either ended with me falling out of the map (and having to restart the game) or getting stuck on a piece of geometry (and having to restart the game). I'm also not really sure how this relates to the jam theme.
As for the music, I think you're probably better off using unlicensed stuff (or honestly just no music at all), rather than songs that are very obviously licensed (The constantly repeating audio watermark in the tutorial made me feel like I was becoming schizophrenic lol). I'd say try to make your own music tracks (Which I definitely think is worth taking a shot at), but as someone who's been struggling to make shitty music for my past few jam entries, I know how much of a pain that can be lol.
