In direct G-mode, the door will not close, and the in-room doorsill gives enough running room to make it up to the invisible ledge.

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.

Jump straight up and shoot with the correct timing. This strat involves shooting a Super diagonally from the correct height while flush against the left wall. Its acceleration will cause it to clip into the blue gate off-screen.

Use a stationary spinjump, or spinjump against the wall and turn around without moving; and shoot with the same correct timing.

Freeze a small hopper to the side and kill the remaining Side Hoppers. Stand against the left wall (damage knockback will align Samus with the wall) and shoot up to freeze the hopper. Jump up to land on it, aligned with the wall. Alternatively, Jump and shoot down to freeze the hopper as a way to avoid damage. Fire a Super just above the door shell to hit the Gate. This strat involves shooting a Super diagonally from the correct height while flush against the left wall. Its acceleration will cause it to clip into the blue gate off-screen.

Run and jump from the safe stair to just reach the door ledge. To avoid walljumping, use a full speed jump or jump from on top of the spikes (stairs or floor).

Jump to the door leading to X-Ray either by jumping from spikes or with a very precise jump. Cross the room by Jumping atop the spikes. Taking enemy damage can be used to reduce some spike damage. The final jump can either be made by jumping from the bottommost spike stair or from the safe stair. Setup run speed atop the spike stair by holding forward to be pushed backward. The safe stair jump is much harder, but can be made without every pixel of runway.

Back up against the wall of the single-tile ledge. Run forward, perform a single arm pump, and jump on the last possible frame. Aim down just before reaching the platform. The arm pump can be performed by pressing shot, or by pressing an angle button (but not releasing it until after the jump).

Crouch on rightmost pixel of the ledge to the left of the door, jump then move over quickly without spin jumping. The timing for the forward press needs to be between 0 and 5 frames after pressing jump (a 6-frame window). Samus's subpixel position is important: X position needs to be at least $64.4000, this is the rightmost 75% of the rightmost pixel. Morph provides an easier setup. From below the ledge, press left against the wall, jump, mid-air morph, and tap left to move slightly onto the ledge.

Requires:

"canCrouchJump"
{
  "or": [
    "canTrickyJump",
    "canMorphTurnaround"
  ]
}

Use the middle section of pipes as a platform to reach the top level, above the Mochtroid. A crouch jump and down grab is enough if the jump begins on the rightmost 75% of the rightmost pixel. Getting into this position can be made easier with a morph turnaround: Spin jump out, turn left then quickly break spin (i.e. with a shot or angle button), morph and press against the upper left wall, then briefly tap left on the descent to land on the edge. Then perform a morph turnaround by pressing right for a very short time to face right without moving. Unmorph and jump to the right by pressing right immediately after jumping (on the same frame or up to 5 frames later), and down grab on the upper right ledge. With the Mochtroid, crouch under the crumble blocks to the left. Holding both angle buttons to aim upward, freeze the Mochtroid while it is on Samus. Jump onto the Mochtroid by quickly pressing down after jumping. When on it, press up to stand then jump through the ceiling.
