Very cool idea! I did struggle finding out which sounds meant what though. You say when the room restarts - you died. But how do we know the room restarted? Is there a sound? Without knowing what the sounds actually mean it does add a lot of trial and error into the game which may be why it hasn't got many ratings (since most people only spend a minute or two on jam games sadly as there are so many to rate). I'd like to see this sort of game expanded on, maybe teaching you the sounds slowly as you work through levels. Could be a very cool mental/audio puzzle game!
