Monument Valley

Monument Valley was the most beautiful, complicted puzzle came I ever got addicted to. All the art very Escher-isk. The shapes, the colors, the puzzle itself. 

Monument Valley is an indie puzzle game developed and published by Ustwo Games. The player leads the princess Ida through mazes of optical illusions and impossible objects while manipulating the world around her to reach various platforms. Monument Valley was developed over ten months beginning in early 2013 based on concept drawings by company artist Ken Wong. Its visual style was inspired by Japanese prints, minimalist sculpture, and indie games Windosill, Fez, and Sword & Sworcery, and was compared by critics to M. C. Escher drawings and Echochrome. The art was designed such that each frame would be worthy of public display. After a closed beta test, it was released for iOS on April 3, 2014, and was later ported to Android and Windows Phone. The game received generally favorable reviews. Critics praised its art and sound design, but noted its lack of difficulty and short length. It won a 2014 Apple Design Award, was named Apple's best iPad game of 2014, and sold over two million copies by January 2015; by May 2016, sales of the game exceeded 26 million.
