Copy/Paste of my videosift post regarding this game:
Bought, played (at night with headphones) and beaten.
Just get the negatives out of the way first: too short & I still found Shalebridge Cradle from Thief 3 scarier/moodier/ more atmospheric than anything this game had to offer.
Positives: Just about everything else. I did enjoy this game better than anything from Penumbra. For me it's no Shalebridge, but damn for $20 and so many years after that experience in Thief 3 this was a joy. I'm glad there are developers out there willing to take risks with these kinds of games.
This game was almost canceled several times, for more information please visit the Frictional Games forums. This game seriously nearly died a number of times. I'm thankful it didn't.
Support Frictional, buy this game and enjoy it. Play at night, with headphones as suggested by the development team. Let yourself get immersed by this game, and don't try playing it like an FPS. Support them, and hopefully they continue to make games of this quality at such a bargain price.
