As can be read in Wikipedia:

Monument Valley is a puzzle game developed and published by indie studio Ustwo. The player leads the princess Ida through mazes of optical illusions and impossible objects. Its visual style was inspired by Japanese prints, minimalist sculpture and indie games Windosill, Fez, and Sword & Sworcery.

And it’s true, the magic behind this game its amazing.
