I dislike the payment method that they are using for the ads. You have to buy a ticket to disable the ads but it's not permanent !!!!! Either you have to pay 4,99 euros for 30 day ticket OR 9,99 euros for 90 day ticket !!?!?!??! This is disgusting. It's the first game that I am seeing this type of thing ! Developers are so greedy I guess..
