Nibbler

Nibbler is a Pac-Man clone for the Apple II.

The player must navigate a character through a maze, with the goal of eating all the dots present within. Complicating the matter, are four ghosts who chase the player through the maze, and cost them a life if they contact the player. In each corner of the maze lies a power-up, which will temporarily make the ghosts vulnerable, and send them back to their home in the center of the screen. The player has a total of three lives, and when all are lost, it's game over. The player advances to a more difficult level if all dots are eaten.
