I was having fun playing this game until the update. Now I need keys to play co-op. Previously you could play as many co-op matches as you want now you can only play 3 a day. That was a bad idea. The changes to the game have forced me to remove it from my devices. And I most likely won't ever download it again. These mistakes have been made by other mobile games in the past and it never worked for any of them. Why anyone thought this would have been any different.
