Description
This puzzle took us four months to create.
It might take you just as long to solve it.

Welcome, everyone, to this very special puzzle.
It was created over a long period of time by both Leomievs and myself.
Both of us had never collaborated on the creation of a puzzle before, but we think it turned out pretty well :]

We do not want to give away too much, but please mind the following:
- If you're having trouble figuring out where to start, follow the arrows.
- Pay close attention to the signage indicating which of the three cubes auto-respawns.
- No tight timing or tight angles, no glitches, no bunnyhopping, etc. All clean logical moves.
- Remember to use quicksave with F6 and quickload with F7.
- You can only place portals on the floor half panels when you're in line with them.
- Using a glitch where a cube passes through a light bridge is not intended.
- Waiting forever for things to magically happen is not intended.

Difficulty: 9/10.
Please let us know in the comments when you think you found something unintended.

Huge thanks to Libbybapa and Narkodes for making their custom items available to us!
Without them, this map may not have seen the light of day.

When you are done here, check out this video that explains the creation process of this map. The official intended solution begins at 22:32.
Good luck and have fun.

The background music is adapted from the track Endless River from my album Irrational Points.[mikeastro.bandcamp.com] Please consider checking it out!

Now I will never have not solved it ever again!
Even knowing the solution I still got tripped up recording the video: https://youtu.be/Cs0Yt-EV1n8
Now I can finally remove it from my queue

@brucer I'm curious what you mean by stacking two cubes on the exit button cheese. I don't think I could try doing it. (I have solved it btw)

@brucer Wow! What an incredible achievement to solve this one without any hints! That is certainly not a feat that many can pull off. Amazing work sticking with it and finally cracking the long and convoluted code that is Isotope. Thank you so much for playing! It means a lot to me to see people spend so much of their valuable time on one of my (co)creations, and I'm sure that Leo feels the same way :cozycrashfish:

WOW!

I first encountered this map playing through a collection on Fumbly Bumbly's workshop called the Best of the Best (great list btw.) After two days of almost no progress, I decided to save this beast until last.

After another couple days, I found a cheesy solution where you stack two cubes on the exit button but I decided this work of art deserves to be solved correctly. I tried so many things that didn't quite work!.When I was away from the computer I would play through it in my head. I'd fall asleep dreaming of WHAT COULD I BE MISSING?! I swore I wouldn't look at any hints, but started fearing I was probably just going to run around the map in circles forever.

After a week, I've finally solved it! Truly a special map, thanks guys! I spent three times as long playing this ONE MAP than I did playing the original game!

@Mikeastro Oh man, thanks for encouragment, that means a lot. Your maps are awesome.

@SpL15 You can most definitely be very proud of yourself for solving this map almost completely without help! Even with the small hints you allowed yourself, that is an incredible achievement. I deeply respect your tenacity - amazing work! :cozycrashfish:

Omg, I finally did it. I had to check the walkthrough again unfortunately since I knew what I had to do but couldn't figure out how to and I was getting pretty annoyed. Placing both cubes at the other side of the fizzlers, deleting the one that's on the funnel button, and then use said funnel to place the other cube on the same button isn't something I could have figured out on my own. I knew that out of sight wall was for something, but my mind keep forgetting about it. I guess I will take this as a lesson that every white wall in this kind of puzzle aren't placed arbitrarily . Fortunately the rest of the puzzle I figured it out on my own, so I'm still a little bit proud of myself. Definitely one of the hardest chambers I played.

@SpL15 Very admirable! I wish you the best of luck on your journey - there is no shame in taking tiny peeks, or asking for a small hint :] Hope you will enjoy the remainder of your time here :cozycrashfish:

Man, this map has been eating me alive for a year or two. I had to check a little of the walktrough to be sure I'm actually using the intended solution. Good to know that I'm in the right track. Not giving up yet!
