This was originally the Campbell Gulpman, which is now marketed by Micromega. It is a variation on the Pacman theme, which involves you in shooting the nasties. There are a large selection of mazes, speeds and skill levels. The graphics are small but smooth, but I think colour could be better used. On the subject of control, the keyboard is poor - cursor, but it does offer Kempston joystick. Generally this is a nice variation, playable but for me not over-addictive.
This must be one of the oldest pieces of software available on the market. Gulpman gives you a choice of 15 mazes which look very blocky, four chasers also of primitive character design, and incredibly, 81 skill levels ranging from unchallenging ghosts to super non-human ghosts. No power pills, but lasers defend you. Fruit and warp tunnels are non-existent. An ageing game, but with plenty of choice.
