Within 1/2 hr of downliad, YOU MUST PAY $ or quit bc u must wait hours for energy. Looks like it would be fun, but you lose energy as soon as you start playing (WTH?). Makes u quit the game until energy restored. Loss of energy is only 1/2 hour from the time I loaded your game!!!! 100% PATHETIC. Only 2 additional way to get free energy is to sign in with FB (NO!) or register email (Got 50 energy. Lasts 5 min) NOT ENOUGH! RAISE ENERGY OR LOSE CUSTOMERS! WHAT A WASTE. Uninstalled.
