An audio-visual sequencer puzzle game with 2.2300745198530623×10^43 possible audio permutations, that's 22 tredecillion in total!
This game has an interesting mix of sound and Dr Mario type gameplay.
Its it not my thing as it is a little mindless, even for a casual game but there are some cool gameplay ideas here that could be fleshed out.
Right now, if feels like a mini-game found in larger RPGs.
I would call this a -very good- interactive screen saver, rather than a game.
Boring.
Depends greatly on mouse quality.
