First thought and experience
First of all, congrats on making a working map, while hearing everything Bets says without getting distracted, job well done.
During my first completion the hardest part of your puzzle was all the amount of elements, and buttons there was. Its really overwhelming. Ik its out of you're control, but for a map in that style, I would really appreciate to have the symbols that are for the door another color or something, because that was confusing. Also the button on the upper part that controlled 3 panels had be to turn off in my brain that the button did nothing else than opening these panels. It would be pretty intuitive that the button opens the panel, if I could see with my eyes, that nothing else in the room reacted to the button. And that's a pretty big part of the chamber, not being able to seeeee. Idk if it was intended, but optimizing the symbols would really help out in a chamber like this, because it takes a long time to understand what does what.
I really liked the fact that you see you need a ball in the upper chamber, then your first thought is to go get the one you put downstairs behind the fizzler, only to realize you can't get it out of there. HOWEVER, the little chamber that opens in the corner of the room really isn't intuitive. Even after going down, I didn't even notice it, neither did I know what opened it. From that, you should know to make it more obvious in the future since its a big part of the puzzle. (Maybe a transparent panel would work?)
In my first play, I also got soft locked. I like went in the first basement chamber, and the fizzler was on, and I couldn't get out, so maybe fix that.
Further thought and ideas
Puzzle changes and optimizations

• Instead of having 2 lasers, what if you only had one, and connected the cube receptor and the "/" button on it. I don't really know if it would be better, nor how the game would let the player know the button receptor doesn't do anything anymore.
  
• Remove the little room with the translucent panel wich appears to be an exit if you ever soft lock, but I never thought of going there since it doesn't look like there is something there, just put in a security, like a trigger that deactivates the fizzler when the player is in there, or a simple button with a timer that lets you out instead of the non intuitive exit
  
• Maybe move the laser receptor that's right over that translucent panel since if player didn't have ot use it, they'll assume it opens the panel (even though they can see the connections). Put it like behind the first cube receptor or another spot that I didn't think of

Final thought
Really well made puzzle, I really enjoyed the way you create wrong first intuition (that is so important to puzzles), so that the player gets the "ahah" moment. But apart from the little gremlins I found, your puzzle is really neat. And I hope I wasn't too rude in my review, and I hope you continue enjoying making puzzle
