I Had No Problems But The Thing I Hate About This App Is Because I Can't Support It Without It Giving Me An Option To. I Want To Pay But I Can't Because It Isn't Even Offline. That's The Only Reason Why I Would Pay For Inapp Purchases. I Would Love It If I Could Play Offline. I Also Don't See An Option To Pay To Play Offline. I Love This Game But I'm Not Playing It Anymore Because It Has No Offline Mode. I Guess I Rather Be A Paying User For Other Offline Games. ^-^
