Ms. Pac-Man Plus (c) 1981 Two-Bits Score.

Basically this game is "Pac-Man", with a few minor differences. The major difference is that the ghosts have fewer restrictions on their movement, making them more formidable. Also adding to the challenge are the different mazes and the fact that the fruit no longer stays in one place, but moves in, out and around the maze. Fortunately there is a power pellet in each corner that (usually) turns the ghosts blue for a period of time, allowing you to eat them for points.

- TRIVIA -

Ms. Pac-Man Plus seems to be the original "Ms. Pac-Man" hack, as the mazes here show up the same way they do in Ms. Pac-Man (each maze shows up in each rack between the intermissions).

While the Ms. Pac-Man hacks are creative with the mazes, they have trouble dealing with other aspects of play. One problem the Ms. Pac-Man hacks have is that the fruit walks along the routes of the original mazes, meaning the fruit is unreachable during part of its walk to and from the center. Also, the ghosts slow down at odd places during the first three racks. Such slowing down only makes sense by looking at the original mazes and seeing where the tunnels would be.

Unlike the Pac-Man hacks, the Ms. Pac-Man hacks don't mess with the scores you get from eating dots, fruit and ghosts.
