Maze games have always been popular on computers and consoles games, and here’s a game that certainly was no no exception.
Radar Rat Race was created on 1981, and converted for the ’64 i think in 1981 or 1982 (I have read conflicting stories on the release year). The game was based on Rally-X , relased by Namco.
With Radar Rat Race, the cars were replaced by mice and cheese. The player guides a mouse through a large maze. The camera follows the mouse and shows only a small portion of the maze at any given time. The player is pursued by at least three rats. The goal is to eat all of the pieces of cheese, shown for the entire maze on a radar screen, without getting caught by a rat or bumping into a stationary cat. Very simple concept but a very addictive game.
