The next room, with the Deku Scrub who shoots nuts at you and the eye switch, is all about timing. The room after this, with the moving floating platform and the spikes, has already loaded. If you quickly shoot the eye switch, as soon as you arrive in this room, you'll get to the next room with the platform in an optimal position. (Ignore the Deku Scrub.)

Don't hit the underwater switch. Just jump out and hurt yourself on the spike bar intentionally - then you can pass through it while invincible. Keep left as it arrives at the far side to save time.

(It is also possible to back-flip over the spike bar but this should be practiced prior to a speedrun)

You don't need to push the block or kill the Skulltula. Climb on top of the block and jump at an angle - CAREFULLY.
