My two main issues are that they don't have you create an account when you start playing, so if your phone dies, as mine did, everything is just gone. Including purchases. Which leads me to #2, customer support, or more correctly, the lack of. I put in a ticket to see if I could get my purchases transferred to my new phone, since the last one died and they don't have you set up an account. That was a month ago. I've heard nothing. Don't get me wrong this is a fun and addictive game but, eh.
