That was a haunting read. The sound design is really what gave me the creeps. It's a little rough in terms of the structure but I played it through twice just to experience all the possibility.
The first time I ended the game in the woods (no spoilers) and the second time I ended the game after Aiden whispered to me (also, no spoilers).
It really did give me the chills but I'd consider fluffing up the writing to paint transitions for scenes, to tell you how things have changed and to sort of immerse the reader in the world. The audio is what did that to me, but not so much the writing. It feels like a really awesome story but I get the feeling that with a little more background and leading the plot around, you could really start to feel haunted by it.
