Crystal Caves  1991

A simple EGA platformer. You play Mylo Steamwitz, a miner who dreams of owning his own twibble farm. You go from planet to planet finding jewels in the mines to make your dream come true. A map screen allows you to play the levels in almost any order. Ammunition is limited, and some levels have reverse gravity, so you have to use your head a bit more in this game than most. The graphics and sound are ugly even by EGA standards, but the game itself is a good diversion. Version 1.0 may cause your system clock to lose 100 years if run from Windows XP. There are 3 episodes in this game, with only the first episode playable in the shareware version.

Episode 1 - Trouble with Twibbles
Episode 2 - Slugging it Out
Episode 3 - Mylo vs. the Supernova
