could there be categories for the different class of racer meaning: Speedster, Trickster, Brawler and Defender respectively

I cant speak for Rose, but I would imagine if the game was more popular it would be a good idea, but as of now, itll just be mainly empty boards and look very overwhelming to speedrunners at least in my opinion. But again I cant speak for him, hopefully he responds.

yeah thats fair

Like Louie said, maybe in the future if the speedruns get more popular, but as for now the amount of categories feels right. I don't wish to overwhelm new runners, but I am always open to discussion about categories at the very least
