Really neat concept! I've never played anything like this so it was a really cool experience. The sound works impressively well, I'm curious how you made that work!
I found the game to be a bit difficult, especially the first time around because I didn't really have an idea of what I was trying to do. A very simple tutorial level might be nice?
Also, would be cool to trace the path my character followed as I stumbled about, I think it'd be really funny to see after the level is finished!
