This is a really interesting concept! Took me about four tries before I finally won, and I thought the music and sound effects were good, There's just a couple changes I'd recommend involving game feel. I think the way the game just suddenly stops when you get hit or fall off an edge is really jarring. I think it'd be good to give the player a second or two before fading it out so you have time to realize why you died. Also, it'd be good to be able to hit a key to restart instead of having to reach over for my mouse ever time. Overall, great job!
