A precise strat that involves crossing both gaps by damage boosting off Wavers. The Wavers are also used for i-frames to avoid taking damage from any spikes. It generally best to use a Fireflea (or two) to quickly boost to the left, in order to boost off the Waver during its first cycle. Waiting for the Waver to return is possible and does not take long, but it gives a different pattern at the left side of the room, making the final damage boost significantly more difficult.

Use a Fireflea to quickly boost to the left, to be able to catch the Waver and boost off it on its first cycle, to cross the first gap. Take two more hits from the Wavers for i-frames, taking the last hit close to the ground while holding forward, to get boosted downward and land on the spikes instantly. Then gain speed using Speed Booster to jump across the second gap; the jump can be done as early as 3 or 4 tiles from the runway edge, or as late as the last frame before falling off: if the last Waver hit is done correctly, Samus' i-frames will last all the way to the end of the runway. If the jump is slightly short, a wall jump can be used to get up.

Using the second Waver cycle to cross the leads to a bad pattern at the end, where the path of the speedy jump will be blocked by a Waver; so it is important to use the Waver on its first cycle.

Wait on the safe block for all three Wavers to come back to the right. The Yapping Maw will not attack while Samus stands on the rightmost 3 pixels of the block. When the Wavers return from the right, use the second one to gain i-frames, hitting it close to the ground while holding forward, to get boosted downward and land instantly on the spikes. Then gain speed using Speed Booster to jump across the second gap.

Dev note: FIXME: gaining a shinecharge on the spikes (and hero shot sparking out the left door) is possible though extremely precise.

Enter X-mode facing left and release forward to allow Samus to walk to the left. Samus' progress can be tracked using the mini-map. When Samus begins to scroll across the screen, this indicates the camera has locked on the left side of the room. At this point (or slightly before), hold forward again to stop Samus' movement. Spin jump and release X-Ray to exit X-mode and jump onto the platform.

Morph, press pause, then press jump and forward just before the pause hits. Unequip Spring Ball to give Samus a large boost in horizontal speed, enough to clear the spikes. It can help to pause a second time to equip Spring Ball again.

Repeatedly take damage from a Waver, using the i-frames to avoid taking any spike hits. There are several possible ways to ensure Samus lands on the safe platform: 1) align with the right-most vine of the group of 3 vines in the background; 2) position so that one tile of the doorway ledge is visible on camera; or 3) take an extra Waver hit, to have i-frames while descending the spike stairs.

Freeze the Waver that gets stuck in the left pit to get to the top ledge. It is possible to do this without a wall jump or any other items but it requires freezing it at a moderately precise height.

Spring Ball jump from the safe spot on the spikey stairs. Moving over far enough left before the peak of the jump is the trickiest part of the jump. There are multiple things which can help get further left: Perform a lateral morph to maintain Samus' horizontal momentum. Morphing and pausing quickly, then delay the Spring Ball jump until after getting a horizontal boost from equipping Spring Ball. Start with a short run and spin jump to move over more before morphing.

It is possible to unequip Spring Ball to get a small Spring Fling, but it can be tricky to get any use out of it and it only helps a small amount.

Jump up to the left door 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.
