It's a fun game but the energy situation sucks. Unless you feel like spending loads of money on this game, then don't even bother. Once you run out of energy, that's it. No more playing. Only way to get more energy is through in app purchasing or watching 5/5 adds. Plus obtaining in game currency is practically a waste of time. Hate to see such a great classic game get turned into just another scheme for money. Shame on the devs and their selfish ways.
