Stay away. Spent real money to buy upgrades for more power only to see the developers tweak your power down to make you purchase more items. No creativity, deceptive premium package. If you are a new player do not invest in this game. For us it is too late. If i knew that they could tweak your power down I WOULD NEVER HAVE PURCHASED ANYTHING. @ GOOGLE PLAYSTORE - A PURCHASE IS A PURCHASE - APPS MUST NOT BE ALLOW TO TWEAK WITH PURCHASES UNLESS THEY MAKE IT CLEAR THAT PURCHASES ARE NOT PERMANENT.
