As the spiral pattern of the orbs in this room seems to make a clear path we can borrow with jumps from an orb to another, it is in fact really hard to pass through the top of the room for two reasons: orbs are quite fast and close between themselves, making it impossible to go through the motif.
Also, using polarities is really tricky because there is so many orbs which may collapse with you. With the trick below, you only use the polarity once and make a better pattern for the orbs to pass through! As I used this technique in hardmode, I can confirm that the room is exactly the same from the normalmode.

Step 1 - Do a pulling polarity right there.



Step 2 - The bottom orbs will slowly rise after passing the pulling polarity.



Step 3 - Be calm and jumb over orbs. Double jump to ajust your flight if necessary. Don't forget to turn on the first switch.



Step 4 - After getting to the second switch, jump on the orbs on the top of the room. Turn on the third switch at the top-right corner.

Last step - Simple fall to the fourth switch. The exit is right there, be sure to reach it carefully without collapsing the orbs or you will restart from this room!

For the hardmode, hold on! It thought it was impossible in the first place, but all you need is practice, patience and make sure to apply these rules:

- If you are tired or something, quit the game and retry another day. It is only a 3 hours long game, you are not in a hurry!

- Remember you have 4 'ammos' for you gun each time you leave the floor. So if you are on a tumbling platform, do a polarity THEN leave the platform: you will just save an ammunition!

- Sometimes, you need to use the ability to cancel a pulling polarity when you reach it. By doing so, you will not longer attract the ennemies. Be fast, and create another polarity to keep travelling without falling down.

- Use a pulling polarity on the blue 'beams' to make a safe place.

- The second jump recharge when you are floating in the air next to a polarity for few seconds!
