Ascend with a long IBJ, then ceiling bomb jump against the speed blocks to overload the PLMs. Falling is very unforgiving. Note that the boyons can be killed with bombs.

Dev note: This is technically doable without canBePatient, but would require double bomb jump, morph, a way to bypass Boyons, and never falling.
