I haven't been really reading games' descriptions before trying them out, so I ended up going into this game without knowing it was horror. Fortunately, I'm rather fond of creepy games (as can be seen in the fact that Bogeyman by Elizabeth Smyth is my favourite IF game). I definitely found this game to be effective in how frightening it was, playing it at midnight making it even more so. I even got clammy hands.
The writing was excellent, as was the graphics, and everything else.
So, if you like horror, then I'd definitely recommend this game.
