The game was released for the Amstrad CPC, Commodore 64, Elan Enterprise 64 and 128 and ZX Spectrum platforms.

This version included a "classic mode" (similar to the original ZX Spectrum version) and an "enhanced mode", which featured new colour graphics, help system, map system, save/resume game feature and remixed music.

Charlemagne "Charlie" Fotheringham-Grunes, the apprentice saviour of the universe, has been asked to find the source of mysterious signals from the Moon[3] which turn out to be a black monolith (a homage to the 1968 film 2001: A Space Odyssey).

Starting on the Moon's surface, Charlie must venture into the caverns below and retrieve eight alchiems[4] (which look a little like coloured crystals) in order to find the monolith.

Once he has collected one of these creatures, he can release it in the caverns when required and it will chew-through any walls it can, revealing new areas of the maze.
