This game is Exidys answer to Pac Man. As you explore one side of the cube, you must fill in the whole side with color. This is called zipping in the game. Walking on a dark trail leaves a lighter trail behind you. When the area around the trail is light the area changes to a color. If you walk back over a line you have previously zipped, it will be unzipped. Avoid the Eyes and other baddies. By zipping around boxes with objects in them, you get bonus points or become a devil and can now go smash heads in like in Pac Man.
