Good game, would like to see it expanded, as it's a bit too easy to get into a rhythm (and too short, which I mean in the best possible way). Beyond that, full screen mode would be nice, and PLEASE for the llove of llord, change the ear-piercing shoe-tying sound effect. The first time I heard it, I closed the game and had to think whether I even wanted to open it again.
Maybe I sounded too harsh, but it really is a fantastic idea and game.
