Complete Every Level with the Words "Badge Challenge", "Expert Badge Challenge" and "POOF! Badge Challenge" in the name aswell as "The Final-Final Test Badge Marathon" (21 levels in total) with any character on a completed save file with all levels unlocked.

Yes! I just thought of this as well, I think it'd be great! Full support!

I like it
