Reward system sucks! Forces you to purchase if you want to proceed. A lot of frustration and too many time-based/lack of reserves obstacles, again forcing you to pay huge amounts. The developer is laughing all the way to the bank instead of looking after his users. Guess we are the suckers for continuing... Now I cannot load the game, lost all my purchases and NO compensation. Just as well because I refuse to PAY one red cent anymore. Or waste my data to download any more from this developer...
