I adore this game. But I was recently relying on data during a hospital stay and this app used more than 4x more data than 1hr YOUTUBE did because of the adverts. That is disgusting. Have adverts by all means but not elaborate interactive ads that are huge downloads. I've turned off background data use in app settings now,so you can say it's my own fault...but it's not like paying for this app to be ad free was an option
