Orbit (Creative Computing)

Published in "BASIC Computer Games - Microcomputer Edition". Orbit challenges you to visualize spatial positions in polar coordinates. The object is to detonate a Photon explosive within a certain distance of a germ laden Romulan spaceship. This ship is orbiting a planet at a constant altitude and orbital rate (degrees/hour). The location of the ship is hidden by a cloaking device, but after each bomb you can determine how close to the enemy ship it exploded. The challenge is to hit an invisible moving target with a limited number of shots.
