Based on Namco's Pac-Man, it includes several variations that alter gameplay.

[1] From the front of the manual: Four cunning Hoonos are in hot pursuit of your Munchman while he races to an energizer to change the attack.

Instead, Munch Man must eat all the TI logos in the invisible maze.

Originally, Munch Man gobbled dots and power-pills, just like Pac-Man.
