This is a direct copy of the pub-type game 'Puckman'. The object is to negotiate a course gobbling up dots. You are being chased by ghost-like shapes which you have to evade, otherwise they get you. In order to be able to kill them you must get to a blob and gobble that, once this blob is eaten the ghosts turn blue, and can now be eaten. Once eaten their eyes live and return to their breeding ground for regeneration.
This really is a superb game graphically and conceptually. I enjoyed playing it very much.
