After the canned response I'd like to give a lower rating for this game, but zero stars are not an option. My network is stable and my device has plenty of memory. The cache is cleared regularly. The ad system is designed to prevent the ad from going away. You are forced into unwanted engagement. If I pay for in-game resources why should I be tortured with ads, too? The ad system is horrible. If not for the incessant and broken ads this would have been a good game. Too bad!
