Great puzzle game! I loved the arrows, although they did seem to take up the entire ending of the game. The last square was impressive and I freely admit to having my rubic's cube sitting next to me as a reference point.
The problem with this game: you think it goes faster than it really does. Most of the time I fail by going too fast, not too slow. To add to the problem, the music is designed to make you want to rush. *Deep Breath*
