I've enjoyed playing this game...but, it's rife with problems. First, the latest updates have really messed with the time boosters, and the amount of items you can get before each container item runs out of time. Second, the energy scheme is horrible. You can only play for a few minutes unless you're willing to spend real money to play longer. Third, the price/reward equation is awful. You have to spend a ton of money for the little you get, and it's simply not worth it. Get it together, devs.
