I just finished Dark Moon for the 3DS! Really enjoyed the ending. The last boss fight with King Boo was a little repetitive, but I liked that too. I still have to get the other Boos I missed, and the rest of the gems. For anyone that has collected everything, is there anything else to unlock besides the extra missions for getting each Boo in a mansion? Is there a special reward for getting 3 Stars on each level?
