Waking up trapped in a tree, with no recollection of anything, you must explore a strange fragmented city floating in the sky to learn who you are and where you fit into the world.

You play a You (short for Youropean), a small humanoid with suction cups instead of feet, which allows you to walk up walls and on ceilings. You must use your unique ability to solve a constantly evolving set of challenges. You will encounter physical puzzles, riddles, ferocious enemies, environmental hazards and more, in an abstract but logical universe that challenges your perception of the 3rd dimension.
