Pyramid Power For The Amiga

Mike Lightstone

This colorful action game, originally written for the IBM PC/PCjr, runs on any Amiga computer with 512K memory. A joystick is required.

The object of "Pyramid Power" is to fill in all the cubes that make up the pyramid by jumping onto each one—while evading some hazardous pursuers. The pyramid is 6 cubes wide by 6 cubes high. If you succeed in filling all 21 cubes, you advance to a new level.

Your pursuers consist of a bouncing rock and a pesky buglike creature. The rock comes bouncing down randomly from the top of the screen, starting over again every time it reaches the bottom of the pyramid. The creature is a little smarter. It constantly follows your every move as you jump from cube to cube. If your player collides with either one, the game ends.

You can also lose the game by jumping in the wrong direction and falling off the edge of the pyramid. This happens frequently when you're fleeing in panic from the tumbling rock or nasty creature.

Type in the program and save a copy before you run it. The small ← character indicates where each program line ends. Don't try to type this character—we deliberately chose one that's not on the Amiga keyboard. The ← character merely shows where you should press RETURN (or move the cursor off the line) to enter one program line and start another. The joystick controls your movement. Plug the joystick into the port next to the mouse port (do not unplug the mouse).

Two Escape Routes

To make things a little easier, there are two special ways you can avoid your pursuers. A pair of elevators flanking the base of the pyramio stand ready to transport you at any time to the apex. To get on the elevator, you have to jump upward from the cubes at the bottom corners of the pyramid. Just get on the elevator and ride to the top. You can use an elevator as often as you like. But be careful not to miss when you jump, or you'll fall off the edge and lose the game.

The scoring system is pretty simple. Jumping on an empty cube is worth 100 points times the number of the level you're on, and elevator rides subtract 100 points times your level number. In other words, cubes are worth 100 points on level 1, 200 points on level 2, and so on. Elevator rides subtract 100 points on level 1, 200 points on level 2, and so on. Advancing to a new level earns a bonus of 1000 points. The program keeps track of your current score and high score, but the high score may reflect the points you gained before your last elevator ride. Finally, Pyramid Power gets harder at the third level and again at the eighth.
