I am playing and enjoying this app. But this is a nonsense, that after 2month it gives update and this causes lagging and small user (2,3,4)gb ram cannot play smoothly. I wouldn't give to greena only one star. But this my compulsion. And in last, i want to say about greena it have a main illness, network connection problem. All other apps working good in same connection but it do not. Nonsense If you could fix it. Please fix it immediately.
