I agree with everyone else - this puzzle was really great fun to solve! And as you say, there are indeed many interesting deductions that follow from this unusual rule set. Very slowly, step by step leading to the solution.
Has Simon really not done this on CtC yet? I could not find it there. It is very well worth it.

Wow, really unusual logic that kept me on my toes. Very satisfying to solve. Superb idea and execution, Evan!

One of the most difficult puzzles I've ever managed to solve - remarkable because I understood right from the start what I needed to do *in principle". Still, for more than two hours I played around and got nowhere, until I finally spotted the break-in. Then I immediately got stuck again, it was still incredibly tough going and took another six hours or so to finish. In the end, my initial approach was proven entirely correct, which means I spent eight hours without much waste - merely implementing (and never broke it), but with every step being monumentally hard.
I suggest recommending this puzzle for Simon's next live solve - should be another feature-length movie. Any seconds?
@polar: Thank you very much for the links, though I didn't end up using CtC and multi-color after all. I did fine in Penpa with single-coloring and pseudo-digits - the poor man's (or should it be the smarter man's) alternative to multi-color.

Glad you all enjoyed the puzzle :)
This is my third puzzle recently with cages that fill the almost the entire grid, its a fun challenge to set this type of puzzle.

One of the maddest, most exciting and extraordinary puzzles I've tried (from you)!
I broke this one so many times and just sweated every time I made a breakthrough, and I screamed out loud when spotting the final breakthrough. Truly an explosion of emotions ;)
A good advice for anyone wanting to try this: use notes and more notes, and probably colors as well.

Can someone please create a CtC link? This puzzle really needs multicoloring.
