I can't speak Danish, but supposedly the brief text description states that the game is a 2.5D platformer "in colour". More intriguing is the plot blurb, which says we'll get "the story of a boy's struggle against evil forces trying to take over the world through questionable experiments on human bodies."

The game is listed for PC, PS3, Xbox 360 and Mac.

Last July Playdead boss Dino Patti warned that his studio's next game wouldn't be ready for a while.
