After obtaining the Blink Boots and returning to the tower via Act One, it's possible to boost up to the upper exit from Wintergarden, bypassing the Maze and lower Wintergarden areas and going directly to Ventilation, where you can proceed to Faradeus.
This boost has taken a couple of different forms: Blink Bouncing from a Volt Walker extracted from Trials, and performing the Overload Glitch in the Tower.
Trials Volt Walker Blink Bounce[]
Instead of using the flower to ascend to the platform of the Maze, you will instead go back into the Trials room. Here you will do a blink to fling the Volt Walker to the left onto the long bar so you can push it out of the room to the left. Don't follow it out of the room or it will despawn. Your goal is to perform a Blink Bounce on the Volt Walker so you will gain enough velocity to launch all the way up to the Wintergarden exit. From there you can drop down to Ventilation and proceed to Faradeus.

Here is an optimized setup that is faster, but more complicated to perform.
This variation touches the Power Plant before entering the Trials room, and uses the residual magnetism to fly across the gap without needing to lower the bar. The Blink Bounce is strong enough to also throw the Volt Walker over the same gap, and the magnetism from touching the Volt Walker allows you to cross back over the same gap.
Next, push the Volt Walker into the tower, and use an Extended Blink Hitbox to cross the threshold into the tower so it does not despawn the Volt Walker. Finally, perform your Blink Bounce to ascend to Wintergarden. Blink into the door frame so you do not overshoot the door and waste time coming back down.

Overload Glitch[]
The Save Manipulation technique of loading two saves at once, actually loads a second copy of the entities in the room you load. This is taken to an extreme by using Bug Report Manipulation to quickly double load a save, summon and dismiss the bug report screen, load another copy of the save, summon and dismiss the bug report screen, load another copy of the save, and repeat. With 5 copies of the bottom of the tower, there's just enough magnetic power to reach the upper Wintergarden exit. However, with duplicate saves loaded, the screen is blacked out, so you must use sound cues to blindly walk to the Power Plant, jump just before touching it, avoid bumping the jutting overhangs of the upper floors, and land on the upper Wintergarden floor. After walking into the Wintergarden / Ventilation area, you may quit to Main Menu and reload the save to restore vision.
Here's a video demonstration of the trick (for what it's worth, since the screen is blacked out).

And using a mod to remove the black screen, here's what's happening behind the scenes:
