There is an official walkthrough somewhere (I think the crystalshard site).
other than that (again, note, I made music for the game, but not all of it), I have to say that it's an impressive game!
The graphics are very well made for such an ammateur attempt!
Story is what everyone loves, and cliché of course, but who cares with fantasy adventure games?
Gameplay works very well
Puzzles have multiple solutions and you can finish the game in various different ways.
5 different endings.
Pretty swell game for a FREE attempt, indeed!
