Also I like that the ball always starts by going toward the paddle - it's a small thing, but the game is much better off doing that then if it were to go in a random direction.
If there was one thing I'd spruce up the main game just a little. I wouldn't have those main menu particles going through the middle circle but maybe they could go around the outside or something like that - or orbit around the outside if that were even possible. But that aside, no complaints.
