Psychosomnium

Psychosomnium is a single player action game. It was developed by Cactus and was released on January 4, 2008.

Psychosomnium is an experiment in illogical puzzles or dream world logic. You'll play the game trying to figure out how to reach an obscure goal. You'll have to do many strange things to reach this goal, like going in directions you wouldn't expect to be able or even putting yourself in unreasonable, and perhaps deadly, peril.
