is it possible to do early bruncheon in 1.3.0 with 2p ?

yes, I believe bruncheon is possible on all versions, 1p and 2p

well on 1.0 you can do it in 1p and 2p normally but 1.0.1 beyond its from the painting to not set a safe spot so you can jump off the island

I think it's an insanity trickjump or something in 1.3.0 since it has to be from the painting, so not in RTA most likely, but the (unrestricted) TAS reroute using it that saves like 7 seconds will use it.

yes you can in 2p but you have to have touched the painting last which makes it hard but in 1p idk if it's possible
