Monster Maze is a game programmed by R. A. Schilling and released on cartridge for the VIC-20 in 1982 (product number 566R).
Monster Maze is essentially a first-person version of the game Pac-Man. The player uses the joystick to move about a maze filled with dots which must be eaten to gain points. Unlike in Pac-Man, where the view is top-down and the whole maze can be seen at once, in Monster Maze the player is looking through the eyes of the creature being controlled as it navigates the maze. The only part of the maze that can be seen is that which lies straight ahead (although the joystick button briefly reveals an overhead map). Several monsters (analagous to the ghosts in Pac-Man) pursue the player. Contact with any of these monsters results in the loss of a "life". However, scattered throughout the maze are special dots which briefly convey invicibility upon the player and allow the monsters to be eaten.
The mazes are randomly generated and contain "pits" which, when fallen into, will take the player into a new and deeper maze.
