In the world record video for the map "Thundernis" there's a ladder flick, which is a glitch as long as I know it, in future speedrun, would that glitch get outlawed or not?

Personally I don't count ladderflicks as glitches (while wallhopping is). But if the community wants it to count as a glitch to seperate it I wouldn't mind.

Thanks for the confirmation zen, although truss flick and ladder flick is the same, do you count truss flick as a glitch?

Nope

Ah, I'm gonna do a video showcasing what truss and ladder flick is then

Above is the video I made on ladder flicks and truss flicks, which one would you allow?

All/both of them

Alright, so now I can do some variation of flicks
