Interesting concept, but I had trouble with it.
I never really figured out what the timing was supposed to be. The sound effects confused me, and the animation of the squares on the chess was a bit jarring.
It didn't seem like it was possible to dodge the projectiles from one enemy (queen?) without moving faster than the rhythm allows.
I did think the way the rook moved was really neat. When it first came on screen I was like "woah, I see the idea now!"
