One life is an idea that comes to mind fast, but its not that fun. And I cant know how many levels are there, so I cant decide if i am good at this game. Grapichs are cool and the particle effects are good but without sound it does not feels rewarding to destroy those blue circles. And finding the optimal strategy is pretty easy, so after finding it, game does not feel that engaging. But my little brother had fun while playing it, and raged a little bit :D.
