When the two main characters are playing Pac-Man (with the cool, giant floor-mounted joysticks) they are repeatedly shown mashing buttons. There's no buttons in Pac-Man, as the only thing you are doing is controlling movement. The same is true later when they are playing Super Pac-Man. Super-Pac-Man has one button ("Super Speed") which must be held down continuously. It would do them no good to keep mashing the button.
