Something that stood out to me this time is the conveying of muscle memory being developed via editing. In particular, the sequence where Gordon Liu is rolling barrels to practice getting across the first chamber.
Every step onto the barrel is edited in a manner that somewhat breaks the smooth flow present in most of LKL's action. Specifically, the sequence where he cuts twice on Liu's feet as he steps on the barrel as it pushes against the normal ethos of editing (i.e. remain invisible and do not draw attention to the cut).
