Pac-Man is more of a driving game than a maze game. As you’re playing, you’re jamming that joystick left  and right, up and down, movements that shifts your right shoulder forward and back, rocking your body side to side. When the going gets tough, and the ghosts start closing in, all of this rocking motion compels you to lean into the game and, whether you realize you’re doing it or not, you’re going to grab onto the game.
