Pac-Man Plus/Gameplay

The basic rules of Pac-Man are unchanged. You must complete each stage by consuming every dot and power pill on the screen. You lose a life by touching a ghost, but you can consume them for a brief period of time after you eat a power pill. Here are a list of the changes.
 * The maze color has been changed from blue to aqua-green.
 * When the ghosts turn blue, they shrink and a green flag appears above their head until they return to normal.
 * The majority of the bonus items have changed (see the table below.)
 * When Pac-Man eats a power pellet, one of the following things may randomly occur:
 * All four ghosts will turn blue as expected.
 * Only three of the ghosts will turn blue, while the fourth remains unaffected, although it will reverse direction.
 * The maze will turn invisible, although the dots will remain visible until the power pill wears off.
 * The maze and all remaining dots will turn invisible until the power pill wears off.
 * The blue ghosts will become invisible, but will become visible again when they begin to flash white.
 * Upon eating one of the bonus items, the ghosts will turn blue, just as if you had eaten a power pill. They will also turn invisible for a short period of time before flashing blue and white.  Unlike eating a power pill, the first ghost eaten is worth 400, and then each consecutive ghost is worth 800, 1600, and 3200 for the fourth and final ghost.  Scoring is normal (200 ~ 1600) if you've eaten a power pill.
