Gain run speed using a platform below the door in the other room. Jump through the door, carrying upward momentum into this room; if necessary, use a momentum-conserving morph or momentum-conserving turnaround through the transition.

Dev note: With HiJump, it is possible to get up relatively easily with only a single tile of doorway runway; so we don't consider side platform strats involving HiJump.
