In 1981, a sequel to Pac-Man was introduced in the form of his girlfriend, Ms. Pac-Man. This sequel continued on the “eat the dots/avoid the ghosts” gameplay of the original game, but added new features to keep the title fresh.- Ms. Pac-Man (Wikipedia)
Ms. Pac-Man is a 1982 maze arcade video game developed by General Computer Corporation and published by Midway. It is a spin-off sequel to Pac-Man (1980) and the first entry in the series to not be made by Namco. Controlling the title character, Pac-Man’s wife, the player is tasked with eating all of the pellets in an enclosed maze while avoiding four colored ghosts. Eating the larger “power pellets” lets the player eat the ghosts, who turn blue and flee.
