neat idea but
not really happy with it, first of all I kind of expected a combination pong and breakout with the opponent being on the other side of the bricks, I like the way you did it better than that idea so it's cool, but needs a much larger play space and two seperate balls as someone else mentioned, also a two player mode.
in case you never noticed in most of these bounce the ball against your paddle kind of games the angle of the ball is drastically affected by what part of the paddle it hits with the edges being really sharp angles and the dead center sending it strait up.
without that you can't aim or strategize but just basically catch the ball over and over again.
