Perform a 1-tap to gain blue speed with a significant amount of momentum. Run through the door, and jump any time after the transition, crossing the room.

Entrance condition:

{
  "comeInGettingBlueSpeed": {
    "length": 1,
    "openEnd": 1,
    "minExtraRunSpeed": "$4.4"
  }
}

Requires:

{
  "notable": "Cross-Room Blue Speed Jump (Right to Left)"
}
"canPlayInSand"
"canCrossRoomJumpIntoWater"

Dev note: This assumes an extra run speed of at least $4.4, though some lower speeds can also work ($3.B through $3.F). The window between $4.0 and $4.3 must be avoided because it would give too much jump height.

Perform a 1-tap to gain blue speed with a significant amount of momentum. Run through the door, and jump into an airball any time after the transition, crossing the room. At higher speeds, it may be necessary to unmorph at the left side of the room while still high in the air, to discard horizontal speed, then pause to remorph (`canPauseRemorphTemporaryBlue`).

Dev note: This needs an extra run speed of at least $4.4. For speed $4.5, it helps to jump early and hold an aim-down pose. Speed $4.6 doesn't seem possible, as you end up too high to land without bonking the door, and too low to have time for a pause remorph? For speeds between $4.7 and $4.9, a pause remorph works. Speed $4.A is difficult but can be done with a last-frame jump, a momentum-conserving morph (ceiling mockball) while touching the second overhang, and a pause remorph. Speed $4.B doesn't seem to work as you can't avoid bonking the first overhang?
