Apple has released a demo of the game Ms. Pac-Man for fifth-generation iPods. The game, published by Namco Networks America and released this past February, is based on the arcade classic of the same name in which players control the pellet-chomping female through a series of mazes while being chased by four different-colored ghosts. The demo of Ms. Pac-Man is a free download; the complete game remains priced at $4.99.
