I hope you will enjoy my thirteenth puzzle.
I would be really grateful for all the comments and ratings.
Normal sudoku rules apply.
No line can either branch or share cells with other lines.
Dynamic fog: The grid is partially shrouded in darkness. Entering correct digits may lighten the darkness somewhere in the grid. No guessing is required.
Arrow: Digits along an arrow sum to the number in the attached 2-cell pill read from left to right.
Kropki dots: Digits in cells joined by a black dot are in a 1:2 ratio (i.e., one digit will be double the other). Not all dots are given.
Killer: Digits in a cage may not repeat and sum to the total given.
German whisper: Neighbouring/adjacent digits along a green line have a difference of at least 5.
Numbered rooms: A clue outside the grid indicates the digit which has to be placed in the Nth cell in the corresponding direction, where N is the digit placed in the first cell in that direction.
X: Digits in cells joined by an X sum to 10. Not all Xs are given.
Renban: Digits along a purple line form a set of consecutive digits in any order.
Equal-sum line: Box borders divide a blue line into segments which have the same sum.

I loved this, great logic! This is also the first time I've ever understood the clue outside the grid constraint, I'm proud of myself for finally understanding it hahah (even though it took my WAYY to long to get it :D)

Exceptional puzzle. There was a bit in the middle where I was stuck for a while but then realised the no line can share or branch rule. Thanks!

That flowed very well! I got stuck for a bit because I forgot that lines can't branch, but beyond that, it was a very smooth solve.

poetry, now? and good poetry.
however, with poetry, you need not obey standard grammar, and rather can emphasize CADENCE.
eg. take "it's what you do in THE dark, unseen", and see what happens if you DELETE the capitalized word.
