A facinating take on an old cliche.
At first, I had doubts about this game. It seemed like another point-and-click "amnesiac in a mysterious house" cliche. By the end, I had realized how creative it really was.
The graphics are very professional. For example, the interior of the safe looked like a safe with a book and human heart stored inside instead of a picture of a safe with a book and human heart pasted on it.
The style is just as good, if not better. As you proceed through the house, you find numerous intriguing things, each of them adding depth to the plot. As you read the journals of the previous occupants, you come to a chilling realization of what the house really is and what kind of danger you're in, and you shiver and think of how you could possibly win even though its just a game.
The sound is very nice as well. Granted, towards the beginning it appears shallow, until you hear the horrifying "Wake up!", the threat of an enraged and charging camper, or the conversation with Vlaew.
The violence is quite prevalent as well, but none of it is unjustified and all of it serves to advance the story, and that's fine in my book.
Proceeding through the game requires nothing but interactivity, making it very high, though the game could use a few more puzzles.
Humor is not needed in a horror game.
Overall, the game is remarkably interesting, and leaves the player shaken, frightened, and with quite a lot to think about.
