Ms. Pacman - Maze Madness [NTSC-U] ISO
[SLUS-01018]

Ms. Pac Man Maze Madness is a "pseudo-3d" maze game. I say pseudo-3d because you can only move in four directions, much like in a RPG where you can't jump. There are some elevated parts in the levels, but they are moved into by other means than jumping.
You obviously play as Ms. Pac Man, moving in a somewhat isometric view. To be clearer, the camera seems to be fixed at a angle, and if i had to estimate it's size, i'd say between maybe 30 and 45 degrees.
This statement is based on a video on youtube, by the user Ninsegalover. The game has gotten quite positive reviews, getting mostly scores of over 75%.

The princess has vanished, and a witch named Mesmerelda plans on stealing the four Gems of Virtue to control the "four wonders". These are 4 areas, each with enemies and mazes to get through. Ms Pac-Man is left with the Pactrometer when Professor Pac gets sucked into a mirror by the witch, allowing Ms PacMan to go to these areas to recover the gems before Mesmeralda does. During the journey, she is guided by video messages and holograms that the Professor put in the Pactrometer. It is up to Ms PacMan to regain the gems, defeat the witch and to rescue the princess.
