The graphics are excellent for a 1989 game. The two paddle concept is innovative, however, you may end up using one paddle and ignoring the other.
The overall layout and physics are well done and the PC Speaker sound is neatly implemented. However, the gameplay is far too slow-paced. It may take a while to finish one level. If it weren't for the slowness (or way too many blocks), this would have been a superb game.
