It's nice. But not exciting.
Great graphics, party-like sound and interface; but I don't find the game quite challenging because it's easy. Easy because the player already has a guidance projectile system and the game doesn't have the force of throw system (you know. The thing where the player manipulates how strong the throw is). I don't know, maybe you intended to have it done like that, since I notice that the velocity of the ball at the moments throw decreases. So bounces don't usually happen.
