Okay gang! This here is an old Epic platformer with some good ideas (ability to aim your shots a bit, good graphics, a world map) and questionable playability. It's actually a pretty good idea for a game, just way too short and the collectathon gameplay doesn't take it as far as it could go.
There were three episodes - I think the first is the shareware, and the next two are "The Secret Chamber" and "Xargon's Fury."
What's odd is that (afaik) not only were the two later episodes sold individually (Ep. 3, which I have, doesn't come with the other episodes), there seem to have been at least three different packaging variations (cue audience "oohing" and "aahing").
So far:
Blue box with purple stone in the center - The Secret Chamber, which is episode 2.
Red box w/ pink dragon faces and a turquoise stone - Xargon's Fury (this is the copy I have, I think)
Same box but with a black stone - also Xargon's Fury
Anybody willing / caring enough to lend a hand on this one? It's a minor mystery, and you're invited!
