The Atari Lynx version of Ms. Pac-Man is a very good pill-gobbler, and – as far as I’m aware – it was only Pac-Man type game to appear on the system, outside of homebrew. It was developed and published by Atari Corporation in 1990.
You can choose which level to play from the main menu, and you can also press Option 1 to change the maze size. This conversion has all the humorous intermissions from the arcade game, plus a few surprises of its own.
Ms. Pac-Man on the Lynx is a fine handheld Pac-Man game. Maybe one of the best.
