The concept is relay nice, its really hard to play anything without seeing but I was able to finish your game with my eyes closed, so well done.

Thanks, I was worried it was a bit too difficult because you have to be pretty close to an edge before you can hear where it is. If I simply increase the distance from which the floor affects the sound, floors you can only get to by jumping would start to be counted too, which would make you think you're further away from the edges than you are. After the jam, I'll try to figure a way to hear more of the floor, and to hear the places you can jump to.
