this game lost all value to me once i ran out of energy. its really annoying when you start getting into the game and then you run out energy. so then my options are to wait for it to refill or use diamonds to replenish it. now here is where my problem comes in, yeah you can collect diamonds here and there but not really enough to afford energy costs. so basically my only choice is to buy diamonds if i want to continue the game uninterrupted which is total bs.
