The game is fun and relaxing. The ads are the biggest downside. I understand that ads are necessary. I like to listen to music or a podcast while playing. A majority of the time my music/podcast player will stop during an ad forcing me to switch apps after the ad finishes to resume whatever I'm listening to. Also, some of the ads now switch to portrait regardless of the phone orientation. It's a minor gripe, but I'm not going to turn my phone to watch an ad I don't care about.
