WOW! This is an old demo. It's even remarkable. It's Halloween in October. It's made with Darkyoshi Engine 4. I wonder if there's a new boss for Mushroom Kingdom Fusion The Gem Quest. I wonder if there's a new character for Mushroom Kingdom Fusion The Gem Quest. I wonder if there's a new character in Mushroom Kingdom Fusion The Gem Quest. I wonder if Shadow, Vector, Leonardo, Raphael, Michelangelo and Donatello are both Available in Mushroom Kingdom Fusion The Gem Quest. This game was called Super Mario in The Halloween Quest.
