Really a well done experience, very good sense of foreboding and tension with events spread out enough to take advantage of that tension buildup.
It might be nice if more side paths were available to allow the player to wander though. It felt a little bit linear in that regard but did a good job at keeping the player moving.
My main critiques are:
The game didn't trap the mouse cursor allowing it to wander outside the game which can result in misclicking outside the window when trying to turn the character.
The default mouse sensitivity was quite high so I'd suggest adding a sensitivity slider if possible.
