Honestly I think this game is terrible. Not only do you have to worry about energy to do anything, but you often still can't do anything with a full energy bar, because the quest are locked behind multiple hour wait timers which makes no sense! You can realistically only play the game for like 5 minutes, every 2 hours or so, unless you spend HUGE real money to skip the wait. It's a nice looking game and cool enough story but, it is totally unworthy of your time!
