Mods already exists which can make game more forgiving. Limiting damage to one is great start. Don't be ashamed to use them on Silksong, developers went hardcore for this one.
I aborted my 3 Hollow Knight attempts because of boss runbacks. Is there a mod that, I don’t know, adds benches before bosses or something? Then I might finally finish the game. I do enjoy hard-but-fair boss fights after all.
