This is honestly one of the best mobile games I've ever played. The art and scenery are breathtaking, the gameplay is fun, and I don't feel forced to be addicted to the game. The ads don't bother me each time I finish a round (unlike most free mobile games) and Zen Mode is probably the smartest feature I've ever seen in a game (though it'd be nice to have a tutorial on how to find it; I had to look it up). This is a beautiful, non-addictive game that I recommend to everyone.
