Done! I got pretty stumped by the theme and decided I’d try to make an unconventional rhythm game and see where it goes. What I ended up with is a game where you have to avoid obstacles that are generated by the note/instrument sequence of any given MIDI file (I’ve included some samples).

Most layouts aren’t terribly exciting or interesting, but it works and I had a lot of fun making it. :)
