The Ultimate edition includes physical content (the game, an artbook, and nine stickers) and digital content (DLC, graphic novel, and soundtrack).
Unique art style and a detailed environment to explore.
Puzzles that break the laws of physics (walking on walls and ceilings), manipulation of the dream world (moving objects, rotating rooms), collecting and using found objects, and avoiding enemies.
Hidden secrets to find (optional, for hardcore players only).
Psychological horror set in a lucid dream, based on a slowly built and frightening atmosphere, rather than violence and gore.
