Play Crystal Caves Online – MS-DOS Game

Game Overview

Mylo Steamwitz must get all the crystals in each screen ("cave") to win that screen, but this requires shooting foes (with the need to replenish ammo), avoid shooting air supplies, find & turn on the lights, and turn switches on or off. Though mostly straight shoot-em-up, the game does involve some careful problem solving, with the risk of mistakes that make completing the cave impossible. He enters and leaves caves by doors to individual rooms from a central cavern, which doors function in-game as teleportation booths.
Each game uses different controls, most DOS games use the keyboard arrows. Some will use the mouse , "Alt" ,"Enter" and "Space bar".
