Its a pretty fun game. I really enjoyed the music and the art style is simple but effective. It fits the theme extremely well (with the levels themselves being patterns and the player having to work around the sequence of colours) and its obviously completely geometric. My only real complaint is how you are dragged away from the action to be shown the next colour sequence; that should really be displayed on a HUD as to not disrupt the flow.
Also massive props for the level editor; I was quite impressed with that! :)
