We found this glitch by complete mistake on the Xbox Version. Was wondering if it's any useful?

Yo, that's pretty wild. That'll most likely be very useful for casual Cuphead players. Might be useful for speedrunners too, but ultimately we gotta see if it's ok with the mods. Might be banned for runs and I don't think it's possible for PC users to do(unless there's another method). Pretty cool find regardless =)

Yeah, casually, it's okay of course. But we've decided to ban it for runs because it sort of violates the rules of not using another save, since switching profiles means you don't have access to the file you're running

Yea I agree.
