My Suggestions for new categories in category extensions:

-death% (Die as fast as possible. Timer ends as soon as you pause the game after dying) -bear%(Save any bear. Timer ends as soon as you pause the game after saving a bear) -talk%(Talk to any NPC. Timer ends as soon as you pause the game after talking. Bosses don't count as NPCs. Shicka doesn't count as NPC) -TalkToAll%(Couldn't create a good name for it) (Talk to all NPCs in the game. Bosses don't count as NPCs. Shicka doesn't count as NPC. Timer ends as soon as you complete the game)

Well, some cosmetics like football cannon or cloud can make speedrunning more difficult, but I don't think there are cosmetics that make speedrunning easier

Can you add platform parkour category? There will be 3 sub categories: 1 section, 2 sections, 3 sections. 1 section means to beat one type of platforms. People will use their own timers because platform parkour doesn't have its own. Timer starts as soon as you start to move from the middle of arcade world and stops as soon as you jump on the platform of other type. You are able to skip platforms and do anything you usually can. There is a bug when platforms are in tubes of the race. It will be forbidden to turn on this race.
