Optically very nice. Also the gamespeed is ok but I encountered several bugs: sometime bricks disappeared without reason, sometimes the ball passed through bricks without bouncing off or destroying them. Once the ball went right through the middle of the panel but I didn't die. Once the ball got stuck on the right side and went up and down the line without me being able to change anything about that.
Things i would recomment to change are: let the ball bounce off the right edge of the screen within the game container. At the moment it disappears and reappears on the right side (not on the left side, though). When and item come rolling down don't kill it as soon as a new item is starting to roll down somewhere else.
But never the less it is a cool game.
