The gameplay in Pac-Man Plus is nearly identical to that of the original Pac-Man. The player controls Pac-Man, and attempts to score as many points as possible by eating all the Pac-Dots in the maze, while avoiding the four ghosts that chase him around the maze and will kill him if they catch him. Eating a Power Pellet will cause the ghosts to turn blue and become vulnerable for a short period of time, allowing Pac-Man to eat them for extra points. (wikipedia.org)
