Amazing buy it

I give four stars because I have a 5s and when I try to buy new units it freezes plz fix now about the game it can get kind of repetitive BUT its very challenging when you get in to it well I picked hard mode and its so fun to watch aliens fly away when you bombard them with artillery its so cool great job guys
