It'd be good to collect videos for the hall speedrun courses in Lakewood town. We should have Level Leaderboards for these speedrun courses

Also, how would All Steam Achievements be different from pendant category? You'll need to do the konami code, grab 'n' go the tutorial, do all speedrun levels, and grab all hearts and books. Dunno if there's any other extra things to do.

well the mods didn't add any of your suggested categories, but I'd also like to propose a category for no out-of-bounds, where the bell out-of-bounds glitch is banned. I think it would make for a more varied and interesting speed game.
