Pac-Man World is set in the world of Pac-Land, where the evil spirit Spooky has stolen the 5 Golden Fruits, plunging the land into darkness. It's up to Pac-Man to retrieve the fruits and restore order to his home. The game takes players on a journey through various worlds, each with its own challenges and hidden secrets.
The gameplay in Pac-Man World is a side-scrolling platformer that allows for more movement than just left and right. Pac-Man can perform a variety of moves, such as the butt-bounce, rev roll, flip-kick, and rev jump, which can be used to reach higher platforms, attack enemies, or solve puzzles. The game also features a password system, enabling players to return to levels they've already completed.
