I don' t think the game is beatable with the current mechanics, it's also very frustrating to play. the fact your ball has to hit a white peg to toggle the blocks forces you to bounce around, but the physics are a bit weird and the ball doesn't always fly in the direction you expect it to. I think it goes to show that games like peggle are fun because they work a certain way, and changing the mechanics of the game also removes the fun factor.
Anyway, congrats on submitting!
