Perplexity

Perplexity is an isometric pseudo 3D maze game which graphically resembles the 1987 arcade game Pac-Mania (both the maze view and main characters) but while it does share some gameplay elements, the game is a much more calm and organised playing experience with the emphasis on puzzle-solving and as such has been described as a 3D version of Repton.

There are sixteen mazes containing diamonds which must be collected and monsters to be avoided. The mazes are broken up with doors that must be opened by pushing keys into them. The keys must be facing in the correct direction. There are other items that can be pushed including boulders that create diamonds when pushed together and black boulders that are just obstructions.

Electron User gave the game a score of 9/10 and "Golden Game" status, concluding "Perplexity is a superb game and will keep you glued to your keyboard for hours... It's good to see Superior still supporting the Electron market, especially with games of this quality". BBC Acorn User said the game is a "classic for your collection, but you may end up smashing your Beeb in frustration".
