You complete the game while getting all moons that are in 2d or are part of a 2d area (like Past the Chasm Lifts in Cascade). Will be like All Sub Areas in that you have to start from a new save file.

Sadly there's not that many 2d moons, only like 28. If we include 2d notes, purples, and shards, it would feel a bit more complete, but it's still thin

if you want to run this gimmicky category, don't let anyone stop you. you should run the game how you want it to be ran, but these categories ultimately aren't very interesting and rarely get ran past the first weeks of creation

Currently, the only CEs that haven't seen a top 10 run in a month are Nipple% 1.2 No Hint Art, World Peace Min Captures, Jumpless, ASM, KFR Invisihat, Festival%, Star%, Talkatoo% non-Any%, Min Cap Throws, and All Bosses... ASM is popular at the bottom because it's an easier WP, and half of the rest has the relevance to potentially get active anytime again
