About Lt. Fly vs. The Spiders From Above
You move your ship horizontally across the bottom of the screen, firing upward at the spiders that crawl down on webs. The main objective is to shoot them all before they reach you, clearing each of the sixteen levels. Your ammo is managed through a separate puzzle grid on the left side of the screen; you match colored blocks to make them drop and release ammunition icons. If you don't clear blocks quickly enough, your bullet supply runs low. The pacing is constant, with a steady stream of spiders that keeps you switching focus between shooting and puzzle solving. It creates a tense, slightly frantic feeling as you juggle two different tasks to stay alive.
