Interesting idea, I think there should be an endless mode where you can just keep matching and matching. I also think it was a little easy, I got 60% on pretty much all my matches, maybe limiting the player to only picking 3 colors or something would make it harder.
Also it seems that a new music track starts playing everytime you start a new game, and the music starts adding up and getting really chaotic. Kind of cool, but way too intense after a while.
