So is asking to be moderator of a community you have no connections to
Wilhelm not appearing: Need to quit out after the death warp. Infinite ammo not working: You probably did it wrong.
This has been asked many times and the answer is always some form of "There's not enough interest". Granted, you're one step above most because you've actually tried a run before asking, but I really highly doubt you will want to continue running it. If you actually do end up doing multiple serious runs, the category will probably be added.
These are no longer unspoken rules. If you click the "More" tab under 1xx% you will see the versions that do not include extra content.
I don't really have interest in running NMG ever, so I don't think I should have much of a say in it beyond the obvious things like clipping. Maybe try to get in contact with the other NMG runner on twitch and decide with him what ruleset you two want then get back to me here.
You can alternatively just rename the old patch folder to "Hollow Knight" and launch through steam as normal
I brought this up in the discord a couple days ago and there were a few people opposed, so it's probably not happening
