Gnasher
BBC Microcomputer System - Released - 1983
Gnasher (aka Scoffer) is a fully featured version of Pac-Man with the usual dots, power-pills and roaming ghosts.
Guide Gnasher around the maze eating the dots and avoiding the ghosts. Eating the power pills enables you to catch the ghosts; the ghosts' eyes then return to the central cage and the ghosts re-materialise.
Once all the dots have been eaten, you move on to the next, more difficult, screen. Sound effects, bonus fruits, four ghosts, tunnels and all the usual features.
