Squeakaliser

The player controls the Squeakaliser, an angry mouse determined to get even with all the cats that have harmed him. The mouse moves in all directions and, at the beginning of each level, must grab the four keys without getting caught by any of the cats that walk about.

After collecting all of the keys, the door in the center of the level opens, revealing a large mouse trap. This must be pushed into the cats, and will take their lives. If the mouse gets caught, it gets beaten up and loses a life. There are two levels of difficulty, which control enemy movement speed.
