I really enjoy, this game. I hate this energy system. But I do understand why they do it. It gets people to come back to their game, they run out of energy, they want to continue, but they can't, they leave the game for a bit, then come back. It also keeps people playing longer, they don't finish the game in one day, they play for multiple days, giving the game a longer life, and if they choose to beat it in one day, they will have to give them money to do so. I understand why they did it, but I don't like it. :/ Really like the game though.
