This game is similar to the classic game of Breakout, where you use a
paddle to hit a ball against a wall of bricks, destroying the bricks.
The main difference is that here the playing area is 3-dimensional.

You have to keep the ball from hitting the floor by bouncing it off
your paddle. You can also direct the ball somewhat by hitting it with
different areas of your paddle (hitting it close to the edges makes it
travel at a greater angle, while hitting it dead center makes it
travel straight up and down.)

The graphics didn't work correctly under Basilisk II, however, it
seemed to run fine under SheepShaver.
