Leaving with upward momentum is possible in three ways: 1) Most easily, with a momentum-conserving morph against the ceiling through the transition, 2) With a momentum-conserving turnaround through the transition, or 3) Jumping specifically with a extra run speed $5.2 or $5.3 and aiming down through the transition. For the first two methods, back into the corner at the start of runway.

Dev note: Max extra run speed $6.5. Using the full runway, the momentum-conserving morph has a 4-frame window for the jump, and between a 2-frame and 5-frame window for the morph depending on the jump timing (with later jumps giving a bigger window for the morph); these windows can be more narrow depending on what is required in the next room. The momentum-conserving turnaround has a 2-frame window for the jump, and either a 3-frame or 5-frame for the turnaround (with the last-frame jump giving the larger window for the turnaround); again the windows can be more narrow depending on what is required in the next room. The aim-down method requires specific positioning to ensure Samus barely clears the door ledge with a frame-perfect jump.

Depending on Samus' speed and position, either perform a speedball or an uncontrolled bounce onto the platform below the Speed blocks. Unmorph and continue holding up in order to break the Speed blocks while passing up through them. The top Speed blocks will respawn; to get on top of them, it can help to press against the wall (to discard blue speed) and then aim down to reduce Samus' hitbox. If available, using Grapple while aiming down can also help. Alternatively, if Samus breaks only the right column of Speed blocks, Samus can use the center left Speed block as a stepping stone. Be careful not to fall through the Speed blocks below as it will result in a softlock.

"canMomentumConservingMorph"

Dev note: Slightly lower or higher speeds could work but with greater difficulty.

Bounce onto the platform below the Speed blocks. Unmorph and continue holding up in order to break the Speed blocks while passing up through them. The top Speed blocks will respawn; to get on top of them, it can help to press against the wall (to discard blue speed) and then aim down to reduce Samus' hitbox. If available, using Grapple while aiming down can also help. Alternatively, if Samus breaks only the right column of Speed blocks, Samus can use the center left Speed block as a stepping stone. Be careful not to fall through the Speed blocks below as it will result in a softlock.

In the previous room, perform a relatively precise 1-tap in order to gain blue speed with momentum in a specific range, then spin jump through the door transition. Depending on Samus' speed and position, either perform a speedball or an uncontrolled bounce onto the platform below the Speed blocks. Unmorph and continue holding up in order to break the Speed blocks while passing up through them. The top Speed blocks will respawn; to get on top of them, it can help to press against the wall (to discard blue speed) and then aim down to reduce Samus' hitbox.

Needs near max horizontal speed coming from about 40 runway tiles in the adjacent room. Jump after the transition. Running a longer on the short runway is more difficult at maximum speed, but will increase the success of the jump. A crisp momentum conserving morph can also make up for a jump that is buffered through the door.

Requires:

Dev note: With high enough speed this could be done without morphing, but it would be more difficult, and Morph is needed to get through the maze anyway.

Requires gaining a specific amount of speed by running a distance equivalent to a runway of 7 tiles with no open end in the adjacent room, to hit a peak in the speed / height relationship. Unmorph to maintain momentum while sliding along the ceiling near the entrance. The spring ball jump is used after landing near the top, to get to the platform below the door.

Jump through the door in the previous room, and perform an air ball soon after entering. With a last-frame jump through the door, there is a wide timing window to do the air ball. With an earlier jump through the door, the airball must be done more precisely: in this case buffer aim-down through the transition and morph immediately on entry, in order to conserve momentum while contacting the overhang.

  "comeInJumping": {
    "speedBooster": "any",

Clears obstacles: door_1

Dev note: There is a 4-frame window for the jump that can work; jumping in the later part of that window is better as it gives a bigger window for the morph. In water physics, an airball has higher base speed ($1.8) than spin jump ($1.6) or aim down ($1.4), which is the other reason why doing it early helps, in addition to how it helps clear the overhang. Doing a ceiling mockball at the top of the room can also work, but it is more difficult, and the frame-perfect jump is required in that case.

Unmorph just before hitting the overhang, to conserve momentum to make it on top.

Dev note: Max extra run speed $4.7. Using almost the full runway (between 3 and 6 pixels from the edge), the momentum conserving turnaround has a 2-frame window for the jump, and a 1-frame or 3-frame window for the turnaround, depending on the jump (with a last-frame jump giving the larger window).
