Overview

The player controls a spaceship referred to in the game as a 'Jet' and has to guide it across a scrolling terrain, battling obstacles along the way. The ship is armed with a forward-firing weapon, and bombs; each weapon has its own button. The player must avoid colliding with the terrain and other enemies, while simultaneously maintain its limited fuel supply, which diminishes over time. More fuel can be acquired by destroying fuel tanks in the game.
