I'm surprised nobody commented on this, but the game doesn't seem to save your progress. Nice game but it sucks to have to stop playing for a while and then have to go all the way through all the cut-scenes and running around the caves all over again to get where you were before.
WTF!! I spent several weeks on this game, then when my computer crashed with the game open, I lost everything, as if I never played. My crash is not your fault obviously, but why are you relying on local cookies to store player data? Will players also have to start from scratch if they log in from a new machine? There shouldn't be more than a few dozen k of text to save for players anyway.
Anyway, even a great game is ruined by losing everything, because then you're not sure you want to go through all that level-grinding again.
