Highly stressful game. Everything costs coins AND energy AND you still have to wait for it to be built. Exotic animals use both elixirs AND coins. The currency is hard to come by. You're given upgrade tools by the hoards, but if you need 5 of each of the 3, you're given 11 of one tool and maybe 2 or 3 of another. It's frustrating and tiresome. If you're looking for a farming game at a more leisurely pace, I'm going back to playing Township. I play mobile games to relax, this isn't it.
