Beautiful animations, good level of difficulty

I really enjoy this games for the animations and sounds. There are in-app purchases, but I dont feel bombarded by them like in some other games Ive played so Im not sure about the lower reviews in that regard. Maybe I bought/downloaded a different version than Im aware of. What I do wish is that there was more variety in the game play. I do find some changes the more I play, but I think the high quality appearance of the games demands more. Thanks.
