Crystal Quest is a single-screen shooter developed by Patrick Buckland and released in 1987, available across a wide range of platforms including Mac, Apple II, Apple IIGS, Amiga, iOS, Windows Mobile, Palm OS, Xbox 360, and legacy mobile devices. The player pilots a small circular spacecraft with the goal of collecting all crystals scattered across the playing field. Completing this objective is complicated by a continuous stream of alien enemies that emerge from portals on either side of the screen. The ship is equipped with an unlimited-ammunition gun for picking off individual threats, while a finite reserve of smart bombs serves as a last resort, instantly clearing all enemies currently on screen. The balance between collecting crystals and managing the escalating alien swarms forms the core of the gameplay loop.
