Ok I played the game since I'm a fan of horror games and here's my review:
Graphics
They were pretty good. Only bad thing I have to say about the graphics is that you over-used the same texture a bit. But other than that, very good. (I especially liked the shaders).
Horror
You did a pretty good job with this. I don't get scared easily, but I'm sure that your horror effects are.. effective to a "normal" person

. I actually jumped at one point when the... no. I won't tell. Play the game yourself, hehe.
The sounds were pretty nice and atmospheric. Only downside was that the background sound was a bit repetitive. You could make that sample a bit longer in my opinion. Also the background sound was not.. how do I say this. Seamless? It has a tiny little break after it starts again.
Story
There isn't much to say about the story but you could add a little more readable things in my opinion. I only spotted one. Are there more?
Bugs, framerate and such
The framerate was pretty good on my rig but in some points the game totally froze up. (Like in that staircase that Paul mentioned)
I didn't find much bugs but one "bug" was that I had to crouch in some stairways.
The controls were OK, but not perfect. Why the heck is the action key "enter"? It's pretty annoying to move your hand away from mouse to push enter. You could easily remove the door texts, or make new ones and change the action key to an F for example.
Overall
It was pretty good. The second best horror FPSC game I've played (Parasite Quarantine being number one). It just needs a little polishing and I'm sure it will be something big, very big.
I give this game a 8/10
