Pac-Man World is a 1999 video game for the PlayStation, released to coincide with the character's 20th anniversary, with Pac-Man going to a birthday party. It is a platform game played in a 3D environment that plays heavily into the history of the character; every non-boss level features a maze that plays by the rules of Pac-Man. Every level is littered with Pac-Dots, fruits and ghosts, and much of the music is modified from early entries into the series.
SFan and lapogne36 abuse various zig-zagging glitches in order to clear the game in record time. We recommend reading the authors' comments for more details.
