Dev note: Setups having more than a 1-tile runway at the door are not considered here, because in that case a regular cross-room jump is possible. Likewise, doing a ceiling mockball through the transition is not considered, since if Morph is available then an airball can be done with just 1 tile of door runway.

Jump and diagonally spark to the invisible platform. There is a small pixel range which lands on the platform and does not touch the boulder. It is possible to do this even below 29 Energy. It requires a last frame jump and then 4 frame spark window. It is more lenient with SpeedBooster.
