So, I’ve been seeing people become mods for this game rather quickly, I also submitted the game to the robloz speedrunning form, so should everyone who has tried to make this game become some sort of mod?

From what I'd expect you got to understand the game enough to detect the slightest of problems that most others wouldn't notice which is why some people who only submit a few runs become mods because they were able to prove they knew the game and can be trusted to notice when exploits that aren't real well known to the general public
