I've been playing this game for over a year now and really enjoyed it at first but it's getting worse with time. The app lags a lot if you play too long, and the new features are irrelevant and very disappointing. The paying / free gems system is definitely the worst idea you ever had for this game because now free gems are useless, harder to get and doesn't even allow you to buy concept photo and stage items anymore. Hope this new idea will be given up real soon, otherwise I may stop playing
