Like a Childhood nightmare
I really do not want to give anything away. The game is scarier than Resident Evil games, clever like Braid, and is certainly a game you should pay twenty dollars for.
It seems like a harmless game at first but when you start getting hunted down and realize that the entire world is out to get you, the creepiness really sinks in. I recommend just playing through the game without going after the secrets until the next playthrough.
The art in this game is pretty amazing too and is worth mentioning. Another great example of "are videogames art?" kind of game. Im really just trying to get my 100 words in here because I really don't want to say anything else if I can help it...It just needs to be experienced.
Just buy it and play it. You will not be dissapointed.
