Ads ads and ads... Basically you can always go further in the game if you watch a couple of ads and unlock some features. I thought... Ok let's buy the no ads pack for 3€ and get rid of this... And still you need to watch ads for the daily challenges which is the only thing interesting after you pass level 10... Don't waste your time here please... I don't know if this 3€ were worth such a bad review for the developers...
