Not balanced and impossible to play without multiple daily purchases. My phone died and i did not put up a shield. Over a matter of hours i got hit 21 times by people who have been playing for months longer even though i had neither resources nor soldiers after the first attack. Instead of preventing predatory bahavior the game tried to extract more money from me by offering to quickly heal for "only" $100. The game is not balanced, it is a pure extraction mechanism pay to win.
