Here's a place to put any meme runs, or runs that don't currently fit into the main leaderboard here. Notably I put a No OOB category in category extensions, which was requested. Currently I have all the messed up eye pain video settings as categories (36p, modern art, indie art), and a few other runs I've seen people do.

Some categories in category extensions may be included in the main board in the future, such as All Bosses or No OOB, dependent on mod team decision, popularity, and further updates to the game increasing the differences between a category and current Any% or All P Rank runs.

If your category does not yet exist: please link me videos of your runs here, in the category extension forums, or through site dm's and they will be added to the category extension board.
