Monument Valley is a simple puzzle game where you lead a princess through an impossible, Escher-like landscape. By moving platforms and bridges, you guide her through the beautiful and mysterious ruins of an ancient civilisation.
I love this game. It is incredibly beautiful, and together with the music and sound effects it makes for an almost meditative experience. The puzzles are fun and there are some real surprises, but they are never so difficult as to become frustrating. It’s a great game to take your mind off of things and to simply sit back and enjoy the experience.
