Pretty good
It's a decent game, makes for some fairly challenging play, and you did good with the transitions between how many paddles you used. However, I do have just a couple hangups.
First of all, no matter how you move the paddles the ball will continue to bounce in one direction (ie: if I move a paddle down quickly onto the ball, the ball still bounces up.) So, maybe work a little on the physics of the game.
And secondly (this may just be me but) I think you should try to find a music loop that doesn't skip between the end and the beginning (sounds like a small detail, but good sound sometimes means the difference between just a pass, and making the front page).
Other than those points this is a fun game that becomes pretty challenging at multitasking. Improve on a few things and I'm sure you'll make the front page in no time. Hope this review helps ^^
