I'm deciding on doing an any% or a 100% all chapters, but thinking about that I already have some of the name tags and bad endings on my current file and wondering if I should use a clean file for 100% and if so is there a way to delete the profile save file (clean slate) or do I need a new account to run it, or i can just do all the endings or interact with the dead bodies of the ones that have name tags

hey im really really new here but if you look under the guides tab you can see how to delete your save! for any i dont think you need to do a full clean but im very new like i said so idk
