Its has given me the chills several times now.
The characters look good but it's the lighting, background, and mood of the game that sets it apart. Very dark.
It's a slow paced game which I prefer. You need to use the flash light all the time which adds to the scarriness when a monstor jumps out and and you need to switch to a weapon before you can do anything.
I've been playing at 12X10, 2xaa, high detail. I'm getting occassional slowdowns usually when there are extra light sources (fire balls... ) and when I enter a new room. It might be my memory thats causing the problems. Still very playable 30-60 fps.
