This was a really interesting concept! Quite frustrating to play before really getting a handle on it but I'm not even sure how I'd change it as the figuring out was sort of the core satisfaction of the game for me. ^^
Thanks a lot for trying my game and your kind words ! I think the best way to improve the game is to give the new keys a less random attribution :) But I agree, figuring out what is the core of the game may be main purpose sometimes :)
