Rats Maze © 1977 Unknown.
A maze game in which the player controls a rat that must escape a maze. Different from most maze games it uses a top-down perspective, but only shows the current room the player is in plus the direction of doors. Every time the player changes room the new room is displayed, but always oriented with the player entering from the bottom side making it harder for the player to keep a mental map of the maze. It's possible to look up a full picture of the maze if the player is stuck. The maze is randomly generated based on a size and difficulty provided by the player.
