Gobbler (video game)
Gobbler is a 1981 clone of Pac-Man for the Apple II, published by On-Line Systems (later to become Sierra Entertainment). It was programmed by Olaf Lubeck who also wrote Cannonball Blitz (1982) for the Apple II, a clone of Donkey Kong.

Gameplay
The player uses the arrow keys to move the character left and right, and the A and Z keys to move up or down.  Each dot is worth five points, while pieces of fruit (cherries, an apple and a lime) are each worth 200.  Consuming the white pellets makes the four ghosts vulnerable for a short time, during which they are colored green and can be eaten (earning 200 points for the first, 400 for the second, etc.).
