that’s quitter’s talk

you have to crouch and then press a to do a backflip

for real tho, if you have a hook with a string on it, you can hook onto the chandelier and pull it to you, then you can step on it and swing by onto the room. If you forget to bring the hook with you, you could always just jump down since it isn’t that far. Just hope that the chandelier is strong enough to hold you for a while.
