I know Luigi gets to be playable in the sequel to Super Mario Maker, so why not Princess Peach? Not Peachette, not Yellow Toad, not Toadette, the real Princess Peach. She deserves the right to be playable, but don't have her get kidnapped in this. It's getting boring! Besides, ratings would go up if you make her playable. Plus, update NSMBU Deluxe to have her be playable so she can get her revenge on Bowser. Even make a tutorial on how to make a Princess Peach's Escape level.
