Crystal Caves Game Review courtesy of

A somewhat average EGA sidescroller created by Apogee right around the same time as the first Keen game was released ... this probably explains why it has been generally overlooked. In any case, it's nowhere near being a bad game, so if you're looking for a good EGA platformer, try it out. Note that it can be annoying at times, since the gameplay predates Keen.
