This is probably really old but I am not really keeping up to date with the Interactive Fiction world: Pac-Man as a text adventure.
Pac-Man was a junkie, eyes oozing pus, haunted by the ghosts of those he’d killed.
They called him Pac-Man because he was always packing heat, lightning-quick on the draw with a personal arsenal second to none. But today he woke up in an alley, all weapons missing but his mouth, an animal, starving hysterical naked, trapped in an unfamiliar maze of mean streets. Needing a fix. Needing a fix like nothing else.
And the ghosts are coming.
You can guess the rest, but it’s well done.
