While there is a filter for yoshi/nabbit, a Yoshi only run has very different movement and routing from a normal ARS run. I've been running it since launch and the majority of levels require entirely different strats. Some levels are even switched around like in W6 where we do airship and hothot instead of itempark and spinjump 2.
I don't think we should be adding Yoshi only as a separate category anytime soon since there doesn't seem to be that much demand for it outside of myself, tho I do think it could make for an interesting CE category later on given how different it is from the current ARS route. (That's if people end up wanting it. If there aren't any runners then there's no point lmao)
GG, Watching the huge 15 year grind for this perfect run was insane. Glad you were finally able to pull this off. Probably one of the best speedruns of all time very-deserved king
