Ya , that would be pretty cool.

It's because the game can be modified in a way that would be almost undetectable.

Not yet sadly . if you are willing we might be able to get one going at a point

Would this be a viable category ? I recently played co op and it was pretty fun and hillarious .

A glitchless speedrun would be cool. at least in my opinion , I am not gonna bash people with a different opinion since I plan to run both and the glitches can be really cool to see/do.
