Played this on PC a bunch as a kid during 90s. Was a fun enough platformer with light puzzle elements to search and find every gem. Heartily recommend it for its exploration and collecting. Expect some trial and error to pass through some areas, but stages aren't long so not much time is lost. A good game to pick up and play when you have a few moments. (There are 3 Crystal Caves games and while the sequels have minor design improvements, each game is the same format and a very basic story.)
