Based purely on gameplay mechanics, the new Xbox Indie Game from Kydos Studio, titled Soul, is simple. The goal: Guide a dead man's soul to heaven. You do this by moving the soul through corridors while avoiding the walls and various hazards. It's the background art and atmosphere that make the game freaky, however. The game is filled with disturbing imagery and pop-out scares, like some kind of nightmarish game of Operation. Check out a trailer after the break and grab the trial version using the link below.
The art style of Machinarium + the evil blobs from A Boy and His Blob + a weird 'narrative' = effing awesome.
So far, I've seen a lot of Indie Games and liked a lot of them, but never enough to truly consider a purchase. This will most likely pop my Indie Games cherry.
