It's a good game for most part besides the lagging. But I've lost overnight all my progress after playing for a year. Just because I didn't link it to a social media. It's not like they are using Facebook servers. And the proof is, till now it was saved. I didn't delete the game or update my phone or even shut down the phone. And there is no easy way to contact them. The email said that my email wasn't delivered. Twice. And they took down the post. I had to write all this comment again.
