1984 Cheetahsoft (UK)

Obviously inspired by Pac-Man but in 3D.
There exists a few more games such as this one, were you move about a 3D maze, avoiding baddies, etc. The difference here are the dots you have to collect.
The game features lifts which allows you to move from floor to floor. Overall I think the game is average, it's a bit on the slow side, probably due to programming options or even the language chosen. This sort of games were not too popular on the Spectrum because the machine itself wasn't suited for them.
