I tried out this game recently after a friend said I would love this game,and MAN was he right :).
The plot is about an unnamed man(the character you play as),who has recurring nightmares about a sawmill and a woman named Anna. As you investigate the sawmill,finding various items and intuitions(basically little bits and pieces of your character's memories),you begin to find out the whole story of just what happened in the sawmill,who Anna is,and just what our character did to Anna,witnessing several horrifying events as you piece together the truth.
The characters are pretty good,especially that wood mannequin that looks like a woman(I can't reveal who the mannequin is because of spoilers),which creeped me out/scared me several times in my 10 hour playthrough. xD
The music is really good,especially the music that plays during when you're outside the sawmill,and the credits themes.
The atmosphere in this game is amazing,where one moment you have that music from outside the sawmill playing,making you feel all safe,and then the next there's some creepy music with that mannequin woman right in your face.
The gameplay is pretty great,which involves solving dif puzzles to progress,and after Stage 2,a sanity meter is added,which lowers the longer you look at a"creepy event"(an example would be looking at the woman mannequin for too long).
The puzzles are kinda challenging your first time through,and the difficulty of the puzzles really depends on if you know what you're doing,and have the items you need(which sometimes your first time through you can miss,believe me I missed about 4 items in Living Quarters,and had to go back there 4 times xD)
Overall,this is a VERY good horror game that I recommend to everyone,even those that haven't played horror puzzle games like this.
9.5/10 from me :)
