Absolutely brilliant.
(those who haven't played the game yet, don't read this - it's a hell of a spoiler)
This is awesome. The ghost-daughter wasn't much at all, but the attic corpse and the head in the microwave were very, uhhh, 'enlightening'. The preloader scared the shit out of me the first time I loaded this. Also, the deranged guy running at you in the underground tunnels was a difference to the rest of the game. Eventually, at the end, I found the puzzle BLOODY HARD (maybe because I'm a dumbass) so I followed the link to the guide and completed it! The way the story loops at the alternate ending is brilliant.
Goriest game I've ever played. Fantastic stuff.
