Can't say that I agree with allowing cosmetic changes such as custom skins. You could very easily replace enemy skins with very bright colours, so that they stand out while doing runs (e.g., bright pink hunter, springgreen smoker, etc). Would bring a somewhat silly advantage to speedrunning the game over unmodified versions.

Really a simple option to get rid of any uncertainty would be to just flat out not allow addons whatsoever.

Imo silly addons make the game fun to run and it's not even close to a point where the "advantages" they could give are gonna differentiate runs.

speedrunning is not about fun you motherfucker turn your add-ons into add-offs or there will be serious repercussions

anyone here

Naw
