This is it. My 40th test chamber. And it's one of my best yet.

This challenging brain-teaser is almost certainly my hardest one ever: you'll have to use all the wit and intelligence you can muster in order to complete it.

Estimated difficulty: Advanced

Estimated completion time: 15-20 mins.

I would like to thank every single one of my friends and followers for always providing infinitely useful feedback through comments, ratings, messages, and videos. Feedback helps me to improve so much, and it allows me to give you more of what you want! So, thank you ever so much, everyone. I would never have made it this far without you. :-)

This was the only solution I could find. Is it the intended one?

I'm wondering what those 3 lasers in the inaccessible little room that can be seen in the picture/thumbnail above are for. They must keep some state of something, but what...

Okay, so after playing this again, believing I discovered an "alternate" solution, which due to the title of the chamber I believed to be the intended solution, then realizing as I was typing it out that it had redundant, unnecessary steps, I'm now quite confused.

Nevertheless, I think I've found a way to complete without cube swapping OR momentum . I haven't seen this method posted here yet - looking back through the comments it seems to be mostly either/or. Furthermore, this doesn't require any glitches or exploits. Even more interesting, every time I've played this level I think this is the solution I've used.

Sometimes when I play this game I randomly select a few chambers I've already played as "warm-ups" before heading into unfamiliar territory. This is the first time I've really thought about the title of the chamber and what it was supposed to imply.

I also suspect my solution is the same as @Miami Mike's -- they also didn't have to cube swap either but didn't mention any cheese. I think it likely Demon Arisen meant for the solution to involve cube swaps but simply overlooked this simple alternate solution.

I suspect the title, "Interchange" is meant as a red herring. When I see two cubes I always suspect that it's what I call a "cube swapper", but there's no cube swapping needed here.

Too bad you never fixed the fling-to-the-exit exploit. It feels somehow natural to use the high portalable panels.
I have the correct solution in my mind so I don't feel like playing all of this again.

Fun level - only critique is its not immediately obvious that theres a second cube.

Nice leisurely run compare to others you made, I have no idea why "Advanced".

Very interesting map, and I like there is more than one way to reach the exit.
