Really cool! Such a neat Idea, and one of my favorite applications of the theme so far. Really, really nice work. And the music you picked was amazingly perfect. One pretty minor note: even though your control scheme was simple and pretty standard, I always think it's better not to make your player figure out the controls on their own. (I didn't see them explained anywhere, sorry if I just missed them). But legitimately, this is a great game jam submission!
I'd love to see this explored further with different obstacles and more levels!
