I hope you will enjoy my seventh puzzle, in which I finally decided to introduce myself!
I would be really grateful for all the comments and ratings.
Normal sudoku rules apply.
Renban: Digits along a purple line form a set of consecutive digits in any order.
German whisper: Neighbouring/adjacent digits along a green line have a difference of at least 5.
Parity: Neighbouring/adjacent digits along a red line alternate between odd and even.
Minimum: Digit in the cell with little arrows pointing inwards is lower than all orthogonally adjacent digits.
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.
If you liked this puzzle, I recommend trying out my other puzzles:

Broken Flashlight in the Dark

Important Hour on the Clock
Positive Symmetry
Solution code: First (1st) column of the grid from top to bottom.

there is one step in the middle that seems far harder than level 1, but it is resolved by basic sudoku in box 9

I struggled with this much more than I expected. Something just didn't click for me. But still enjoyable, Mid-game i just lost the plot somewhere

I'm embarassed how long it took me to remember the number room clues. They are so big and outside the grid how could I miss them?? Got rather far without them but then stalled for... a time I will not reveal. Thanks for the puzzle.

Lovely solve! Makes me wish we had a 1.5-star difficulty rating.
