TL;DR: This game was pretty neat.
Thoughts: My computer is older, so this ran like potato on my machine. I didn't continue past the first area. From my experience and watching some other playthroughs, the base walking speed is too slow; maybe you could increase it to the current "sprint" speed. The game is pretty, the atmosphere is suitably scary, and the sound effects were very good, although the footsteps are loud, and the lightning sound in the first area is so frequent, it gets annoying after a while. From the other playthroughs I've seen, I like where the story goes; it reminds me of "The Beginner's Guide," but with enemies.
It would be very helpful to have a "Settings" option in the game menu, so the player could adjust to a lower resolution or windowed mode without needing to quit out of the game and re-launch it (which I did, several times, to see if I could get it to run better). It would also be nice if the menu had a basic overview of the controls; I've never seen a game that makes you hold "ESC" to be able to leave the game. (If you do set up the game to run in a small window, the text for the Escape menu does not get smaller; you literally cannot click to leave the game if the window is too small, because the text is below the window.) There is a glitch in the cabin bathroom; you can see the floor texture through the bathtub.
Overall, I think this is much better than most indie horror games, with some really good atmosphere -- it just needs some polishing.
