EngineCrystal Caves uses the same game engine as another one of Apogee's games, Secret Agent.
PatchOctober 24th, 2005, Apogee released patched v1.0a shareware versions (and patches for registered versions) of old play-alike games Crystal Caves and Secret Agent after discovering that quitting these games under some installs of Windows XP (an operating environment that wasn't a twinkle in Bill Gates' eye at the time of these games' release) in some cases set the system clock back a century!
Credit for the fix goes to Peter "DOSBox" Veenstra and Crystal Caves' original programmer Frank Maddin; as the press release likes to point out, patching these titles up to 14 years after their initial release "has to be some kind of record."

- The title of Part One of Crystal Caves, 'The Troubles with Twibbles is very much alike to an episode of Star Trek: The Original Series, which had an episode titled The Troubles with Tribbles. Scott Miller - the game designer - is said to be a fan of Star Trek.
- There are numerous references to another Apogee platformer - Commander Keen, hidden in the game. Keen is listed on the default high score list, his famous helmet can be found many times throughout the game, and there is a mention about Yorp herding.
SharewareLike most Apogee platformers Crystal Caves is actually a trilogy. The first part of the trilogy is shareware, the other two parts are not. The names of the three episodes are:
- Vol 1:Troubles with Twibbles
- Vol 2: Slugging it out
- Vol 3: Milo versus the Supernova
