This game is starting to become only about money. Why cant't player earn energy and gems for digging? There are very few blocks that have energy or gems. Even in the green ring room. I received very few gems in that map room. You advertise that it doesn't cost much, but who wants to wait over 2 hours to get full energy. Then you throw in blocks that are for 2000 energy points! Why can coins buy gems? I do love this game, but I am not going to spend the money needed to continue play.
