So I am curious after looking at the rules for any% and 100% about why it stops at beating Mr. B instead on the point were it transitions to white to the cutscene just before the credits, or even when you finish on the last dialogue before that transition. Since you still have control over the character in the next part (where you can still even get a sticker) until you finish all the dialogue to even get to the credits.
I'm just curious since its different than the rules for most any% or 100% that I have known in speedrunning where it ends when you can no longer control the character anymore or at the moment when there is nothing at all that can be done just before the credits roll (Example: the exact moment you k.o. the final enemy in a fighting game).
