Pretty good concept.  It reminded me of a Blair Witch kind of thing.  I found three of the papers and what I assume to be the "exit" (the place with the rocks with runes on them, not the ones stalking you).  But I couldn't find the 4th paper.  I looked for a good 30 minutes but kept finding the things that had the other papers.  Maybe making it a little easier to find all the papers would be my only suggestion.  And maybe have the character move a little bit faster.  Over all, pretty good game!
