REASONS TO PLAY MONUMENT VALLEY

In order of importance
  1. Frank Underwood plays it
  2. It's genuinely aesthetically pleasing
    Much unlike the pipes and circles of flappy bird
  3. The music
    You simply can't play the game without the music
  4. Mind-blowing relativity-based aspects
    Did M. C. Escher come back from the dead and design this game?
  5. It probably costs less than the mocha you bought this morning
