Synopsis

While exploring deep space, you encounter invaders from a bizarre geometric universe attempting to breach Earth's dimension. Their force fields trap your ship along the outer edge of twisting geometric tubeways, where you must destroy enemy craft before they can invade your reality.

Players control a target-shaped vessel that moves around the perimeter of ever-changing geometric shapes while battling Homer and Seeker enemies, worth 100 and 200 points respectively. Destroying all incoming ships advances you to the next stage, introducing new shapes and increasing enemy numbers. Remaining time at the end of each stage awards bonus points.

A constant time limit adds pressure. If time expires, a deadly creature trapped in the corner of the screen escapes and relentlessly hunts your ship. Players begin with three lives and earn an extra one every 20,000 points. Lose all your vessels, and the game is over.
