Peach's Castle introduces more complex enemy types and environmental puzzles. You'll encounter Supporters, who can heal enemies, and Peek-a-Boos, who are immune to frontal attacks. This world emphasizes the importance of flanking and using character skills to control the battlefield. The puzzles here often involve activating multiple switches or using specific character abilities to progress. Keep an eye out for hidden areas that contain valuable Power Orbs and weapon chests. The difficulty ramps up, so ensure your characters are upgraded and you have a good understanding of their synergies.

While the Supporters in Peach’s Castle rely on tactical healing, Mario Kart Tour utilizes a more chaotic item-based support system to influence the race's competitive momentum.
