In Squish, the player controls Ziggy the Mazeman as he avoids being squished inbetween moving walls and the edge of the screen. The walls will move according to a direction as indicated on the top screen, which changes every few seconds. A point is earned for every second the player stays alive. A mostly unique feature of Squish is that the top screen is only used for information suuch as score and direction of movement, and the playing field is only on the bottom screen.
