Maze (F) (1986) - Amstrad CPC - Puzzle, Arcade.

You are locked in a 10-story maze, from which you must escape as quickly as possible. The exit door is closed by 3 padlocks controlled by keys stored in boxes randomly placed in each of the 10 floors. Your job is to find the 3 keys. To open the chests, you must first find the combination of 5 letters. To make matters worse, you are chased by mischievous ghosts, who steal the keys from you and put them back in their place, in the safes.
