I've done it! Just Pacifist Run + get hit by as few credits as possible. Then the door will open right up!

You have to dodge all the credits after the True Pacifist ending. It's tricky, but doable if you believe hard enough!

True Pacifist ending + zero hits during credits = secret door unlocked. Good luck, you'll need it!
