canMomentumConservingTurnaround (Very Hard)

Uses the uninteruptable frames of turning around in order to continue moving after hitting a solid object. Can be used to make it through an opening door, or barely just past a ledge. It is often beneficial to be in a downward pose when hitting the ceiling, in order to shrink Samus' hitbox to delay contact.

Requires a runway of at least 6 tiles (with no open end) in the adjacent room. Use a Cross Room Jump into Water followed by a delayed Momentum Conserving Turnaround.

This underwater walljump is very long. Some jump assistance, cross room jump, or a flatley jump from the door frame is needed to get to the first overhang. The cross room jump requires an adjacent runway of 3 tiles (with no open end) with HiJump disabled. Perform a turnaround just before hitting the ceiling.

Top Right Door

It is possible to jump to the top door using a runway of just one tile with Speed Booster and no HiJump. Requires a last-frame jump and down press that is late but not immediately before the turnaround. With a second-to-last-frame jump it is still possible but more precise.

Entrance condition:

  "comeInJumping": {
    "speedBooster": true,

Run and spin jump from the platform in the room below, gaining horizontal speed but without bonking the door frame. Perform a momentum-conserving turn-around to make it around the corner of the ledge above. With limited runway for gaining horizontal speed, the timing of the jump and turn-around may be very precise.

Spin jump from the platform in the room below, pressing right against the door frame through the transition. Perform a momentum-conserving turn-around to make it around the corner of the ledge above.

Do a low spin jump and press against the right side of the door frame. Wall jump as low as possible, jumping as soon as possible after moving away from the wall. Immediately turn back to the right and try to press against the door frame again before the transition, while maintaining spin. After the transition, typically a momentum-conserving turnaround is needed to avoid bonking.

Quickly shoot to break the shot block and then do a momentumConservingTurnaround to ascend into the little region. Another movement item will be needed to get closer to the crumble blocks.

Use Screw Attack to break the bomb block by entering from a non-water room with a spin jump, and make it all the way through the top door. This uses exactly 14 tiles (with no open end) - more rises too fast to do the trick, less does not have the height needed to reach the door. Use angle to break spin, then a momentumConservingTurnaround as early as possible, right as you pass the above tile horizontally. Using the background for positioning may help. The second momentumConservingTurnaround is as late as possible, just before touching the above platform. A third momentumConservingTurnaround is used on the door as it is opening.
