Gain run speed using a platform below the door in the other room. Jump through the door, carrying upward momentum into this room.

          "This requires a last-frame jump and specific horizontal alignment in order to make it past the overhang in the next room.",
          "A way to get a correct starting position is to jump, press against the ceiling overhang near the end of the runway,",

Dev note: With Morph or Speed Booster, even a 1-tile doorway runway is enough to make it up relatively easily; therefore, we don't consider side platform strats that require either of those items.
