Explore Mode (All Modes): Self-explanatory. Complete all modes in Explore.

All Adventure Worlds: Complete all levels in every world in Adventure.

All Co-op: Complete every level in Co-op.

All Modes: Complete every mode in every area (Explore, Adventure, Co-op)

100%: Start from a fresh file and get 100% as fast as possible (have to show 100% on file for run to count)

Also, two other categories could be All Expert Explore Challenges and All Master Explore Challenges.

I’m just now realizing how long 100% would take, but that’s the fun in it.
