In Monument Valley, the player leads the player-character princess Ida through mazes of optical illusions and impossible objects, which are referred to as "sacred geometry" in-game, as she journeys to be forgiven for something. The game is presented in isometric view, and the player interacts with the environment to find hidden passages as Ida progresses to the map's exit. Each of the ten levels has a different central mechanic. Interactions include moving platforms and pillar animals, and creating bridges. The player is indirectly cued through the game by design elements like color, and directly cued by crow people, who block Ida's path. Critics compared the game's visual style to a vibrant M. C. Escher drawing and Echochrome. The game includes a camera mode where the player can roam the level to compose screenshots. It includes filters à la Instagram.
