Unfortunately...
...there are a lot of problems with the way the ball behaves. In a game of Breakout, ball behavior is critical; otherwise, even the basic gameplay is compromised. I noticed that sometimes the ball, upon hitting a block, we move in an entirely different direction. Sometimes I saw the ball deflect off nothing. Such erratic behavior is not acceptable in a Breakout-style game. Other than that, the graphics are bland, and the sound effect for the ball hitting the pad is annoying.
