I think this is actually a pretty interesting concept and I really like the idea behind the game.
My main problem is that the way the in-game physics are set up, it's possible to position two paddles in such a way that the ball bounces back and forth between them infinitely until the points goal for the level is reached without having to move anything. When set up right the ball will travel the exact same path back and forth between the two without ever deviating or needing to adjust the paddles, which makes it significantly less challenging.
