hey, i too got stuck on the same area. if it wasnt for youtube, i wouldnt have known how to get those things you are suppose to get. :-)
i thought that arriving to those 4 different endings should have been much more different. the alternative path was too simple i thought. would have ruled to have some different levels for each path or something.
oh yes, i hated those damn golum like dudes. cant remember their names, been months since i finished it. but they always killed me, damn them all :-)
but anyway, the game does rule hell.
