ehm, final version?
at least the main game sites download version has 2-3 unreachable locations in it and no (let alone different) endings, are you sure the game is done already? O_o
Also see my comment there
cant say I ever got to a game over or game won screen, like I did what was visibly doable for me and the unfinished stuff (other side, island of whatever) seems to be the only thing left.
will go around the game once again though, still have that graveyard key that I dont know the correponding graveyard to :-)
