Here's my detailed review

(I gotta be detailed or I don't feel accomplished ;c)
Gameplay-
9/10
*It could use "some" improvement to be honest, I mean it's tough to get to some of the areas, the english grammar in your subtitles, trailers, and graphics is off (not a super big minus but it'd be nice to be easier to read :x)
Visuals-
9/10
*Yet again, it's good but there's something weird with the demon :/ I dunno, it's scary but it's not SCARY if you get it. xD I guess it's just a little too cartoony to scare someone who plays left 4 dead and killing floor 3 hours a day

if you made the demon's textures more realistic then I'd definately give visuals 1000/10 ;D
Lighting-
8/10
*I like the lack of lights as a horror theme, but the problem is it's just "too" dark. I mean have you ever been in a blizzard before? Light is trapped between the clouds and the ground making it very bright outside even in the middle of the night. Adding in a little ambient light wouldn't be too bad an idea, or making some really high quality lightmapping. You need Just enough light so the player can see the cool features of the game, but not so much that it retracts from the overall experience.
Music-
0/10
*No points for stealing Penumbra's music :x especially since I'm a Penumbra fan!
Structure-
9/10
*Some of the areas are a little confusing but overall I like what you've done to customize FPS creator to make this! If you made some of the levels a little easier and bumped up the difficulty of others then you'd have a 10/10 here too.
Overall-
9/10
*I like the game, it's got a good grasp on the horror concept, but remember to fix some of the grammar issues in the letters/to do, and maybe reskin the demon-thingy with something a little bit more...realistic to get the right effects.
And I know I didn't give anything a 10/10 ;p I'm a super tough critic when it comes to those kinds of things! that's why I've been working on my own project for like 6 months and still haven't passed the initial designing phase
