This must be the most beautiful numbered rooms puzzle out there. Really enjoyable logic. Hard but doable: 4 for difficulty, 5 for beauty.

Fantastic! Very tricky right after the opening sequence, and I kept breaking it for dumb reasons, but in the end it was an hour very well spent. Highly recommended

This has gone straight into my favourite ever puzzles. The logic within is subtle and so rewarding to find. A really spectacular puzzle, thanks so much Tesseralis!
P.s. @Solvers, don't listen to the puzzle, you're good.

I had terrific fun with this puzzle.
Really interesting logic from beginning to end,
especially with deciphering how the final few letters line up with the numbers.
Great work!
