The object of Cuthbert's walkabout is to light up all the squares on the lunar pad. You are faced with a large grid of squares and, using the joystick, must direct Cuthbert around activating light switches at the four corners of each square, scoring 10 points per switch and 50 points when the whole square lights up. After lighting the entire grid (score 1,000 points) you proceed to grid 2 and start again. Sounds easy? Well, it's not.
Cuthbert is hounded by a group of ruthless moranians, semi-intelligent beings who try to bump off poor old Cuthbert. If Cuthbert takes too long the chief moranian appears. He is more intelligent, quicker and more difficult to avoid. Cuthbert can leap over any moranians approaching him but must take care not to jump too soon. The moranians do not take kindly to him landing on their heads.
A rather repetitive tune accompanies what is a reasonably good game. I like Cuthbert, a lovable little character who could develop a real cult following. Oh, and you can record your high scores in Cuthbert's Hall of Fame.
