READ THIS.
Ok so I have been playing this game for a while now, and ZERO LAGS. UNTIL. I spent two dollars on the starter pack of this game. While it was downloading, and after I had already sent the money, it CRASHED. Now, FOUR DAYS LATER I try every day and it refuses to let me in. It crashes before the loading screen even finishes! So yeah. Fun. Very addictive. BUT DO NOT BUY ANYTHING ON THIS. Also READ THIS: if you do buy something, and it starts crashing you out like it did for me, then deleting the app and getting it back wont work. It still crashes. I WILL RATE ZERO STARS IF YOU BUTTS DONT CHANGE THIS.
