This is a version of the old "Break Out" game developed for the early computers.
The object of the game is to destroy all the blocks, on screen.
If the ball hits the ground before all the blocks are gone, you loose the game.
If all the blocks are gone before you hit the ground, you win.
There are four levels, each level has an increase of bars, till you get to the fourth level, where the bars are bigger and closer together.
