For a free point&click game is rather good I most say, but IMO is hardly a "horror" game, because is very light on that aspect to my taste.
There's also to much backtracking and the character doesn't run, fortunately you can double click on doors and it will teleport the character to them, you can also skip dialogues, what is always nice.
Some puzzles have more than one solution and you get different achievements for solving them each different way (for those that care about achievements... I don't) also to me at lest, some of the puzzles were rather difficult.
Anyway it is free, so play it.
