After all this effort for getting our paddle to move, the game still doesn't have much oomph to it. It's very easy to keep the ball bouncing because there's nothing to send it spinning off in any crazy directions. At least in Breakout or Arkanoid, you had interesting angles to work with. Our game doesn't have any walls to angle off, but we do have that paddle.
What if we angled the paddle as the player moved it around? An angled paddle would make the ball bounce in different directions and keep the player on his toes.
