I think you can do a lot more presentation wise. I know what you are getting at with it but I found stuff like the in-game font and the menu screen really off-putting.
Other things you notice are trees that kind of repeat themselves and rather empty, feature less levels. I think that a horror game works way better whenever you get sense of immersion from the world and I don't quite find that here. To me it all rather looked like a first draft.
Your sound design is pretty decent!
