Play Crystal Caves Online

So Crystal Caves is this weird little MS-DOS gem where you play as Mylo, a dude who’s gotta collect all the crystals in each cave to move on. Sounds simple, right? Nah—you’re juggling ammo, trying not to accidentally shoot the oxygen tanks (oops), and flipping switches to turn lights on while dodging or blasting enemies. Mess up a switch or waste too much ammo, and you might soft-lock yourself, which is equal parts frustrating and hilarious.

The caves are these self-contained puzzle rooms, and you hop between them through teleporting doors in a central hub. It’s got that old-school charm where half the fun is figuring out how not to screw yourself over. The shooting’s straightforward, but the real challenge is managing resources and not panicking when you realize you missed a crystal behind some weird wall.

It’s one of those games where you’ll either love the jank or rage-quit after the third cave. No in-between.

Each game uses different controls, most DOS games use the keyboard arrows. Some will use the mouse , "Alt" ,"Enter" and "Space bar".
