The game design is a good idea and the game is so relaxing. I can feel the passion the developers put into such a small game. But there're some small problems on this game. I got smaller resolution on non-full-screen mode so everything were blurred. The click/touch area of flippers are not so good. They're too strict to click/touch. They should be both half of the screen. I sometimes actived flippers when I touched on opposite side.
