PURE PAY TO PLAY.. It is a great game to play as long as u have a newer phone or tablet that will handle it. Update.. response to developer.. how exactly? The insane amount of resources to upgrade buildings to higher levels would take days of constant game play to reqiure without spending money. Plus everytime another player hits your base u lose all those resources. So explain how in the hell can someone stay on same level as those who can afford to pay without paying? I uninstalled app.
