Ms. Pac-Man Maze Madness

Professor Pac learns that the witch Mesmerelda has used black magic to seize control of the enchanted castle and wants to steal all four gems of virtue (generosity; truth; wisdom; courage) from there to control the "four wonders" (areas of Pac-land). He creates a device called Pactrometer that allows Ms. Pac-Man to go to these areas to retrieve the gems before Mesmerelda gets them first.
