Finished it a couple of times (skipped a lot of text the first time so I went again) and didn't realise there were several endings to be honest - I think I just did the same things both times though, thinking there was only one path.
I think it ended when I fell down a river, woke up and decided to head back? How many choices are there? Might have to retract my criticism, I genuinely thought there was only one path to follow. I'm guessing the paths depend on how many random items you investigate to get information?
