This is just another progress update as Mario comes along. First order of business, Bowser's special class uses the sprites from a boss from Mario & Luigi RPG 3!! This class will be a secret and be very powerful. It's one of those rewards for those who go the extra mile. Once all his moves are finished there will most likely be another installment of Shroom Stuff to show him off. It should be fairly impressive.
In terms of progress, the main story is nearing the end of the 6th sage, but there is still a good amount of side things we are still adding. Percentage wise, I would say that we are about at 75% of the game being complete. You should still expect it during this summer.
