There should be a Gliitchless% category, the WRs over the past, well, forever have used insane glitches, they arent hard to pull of but still
On it's own glitchless isn't a bad idea but it becomes extremely messy when you try and implement it for Karlson 2D. The issue is that a lot of the glitches used tread the line between a glitch and just exploiting the game. The two best examples are slide boosting and L-barrelling:
Slide boosting isn't so much of a glitch but more us just exploiting the fact that you get speed from sliding, we certainly aren't using it as intended but it's built into the game to work that way.
L-barrelling is the same - That certainly wasn't intended and most likely Dani just forgot to remove it so that's built into the game and yet here we are using it.
The only thing you could definitively point down as a glitch is spam shooting. SO if you just ban that then you've really just created standard with out spam shooting which isn't really deserving of it's own category since it's so similar. Also there is the question of whether or not it would even be ran. Literally nobody is running gunless and only like 4 people (myself included) are actively running Karlson 2D at all.
Sorry for writing a whole novel but tl;dr good idea but it's not for 2D.
