My idea of a new category:

Shadowless + Kill all ennemies

forcing the player to find strategies to quickly and efficiently kill all the killers in a hard way (kind of like hardcore) and we could also include deathless to this category but i don't think it'll matter.

I will take that i mind but for now there's no enough participants to the traversal speedrun community to make more categories.

This, could be implemented. We need at least 70 player's here though.
