In Doomed PETSCII Pacman, almost everything works a little bit differently. For example, eating power pellets can have terrible effects, but they are needed to level up. Eating ghosts is deadly in any case.

Unlike conventional Pac-Man with Blinky, Pinky, Inky, and Clyde, Doomed PETSCII Pac-Man also has Zinky and Drinky. Don't expect to enjoy this game – it's not designed for that.
