Descpription:
The objective of Off the Wall is to score as many points
as possible by destroying square blocks in a neverending series of levels.
The player controls a paddle using an analog knob or a joystick (depending
on the machine configuration). The paddle moves along one edge of the playfield,
and a ball flies around the playfield and bounces off the walls and the paddle.
When a ball hits a block, the block disappears (unless it is indestructible).
A square exit is placed on the screen, and directing the ball into this exit
causes all remaining blocks on the screen to self-destruct, awarding
bonus points and advancing the player(s) to the next level.
