Hints:
Break-in Hint 1: Where does r3c8 (circle of the arrow) go in box 9? Ask the same question about the other circles.
Break-in Hint 2: What does it mean for r3c3 if all the other arrow circles are different digits?
Mid-solve Hint 1: What digit(s) can we put into r3c7 to give a valid arrow total?
Mid-solve Hint 2: Where does r2c8 go in box 1? Can r8c2 be the same as r2c8?
Mid-solve Hint 3: What digit(s) must appear on an arrow summing three distinct digits that cannot sum to 9? Where do those digits go on this arrow?
Late-solve Hint(s): Follow 5s counterclockwise around the grid. Check restricted columns and rows like r4 and c4.
Lösungscode: Row 2 followed by column 1 (left to right, 18 digits, no spaces)

Really nice. What a great series. It's more of a 2.5* I guess so I've rated it 3 to even the scales slightly.

Very nice! Indeed challenging for a 2-star puzzle, but that makes it perfect for anyone looking to expand their solving comfort zone

purpl: Indeed it is definitely a 2.5 if that were a thing, I am happy it has been well received despite that! Thank you :D

This was the most challenging 2 star puzzle I’ve ever done. All of the logic was extremely fun to figure out, even though some of it really stretched my brain! It left me feeling like I’m stronger with my puzzle logic then I was a couple hours ago, and that’s what makes a truly great puzzle experience. Thanks!

Elegant discovery of Sudoku geometry ! Thanks, @ purpl :-)

purpl: Hehe thank you! I don't know if it is a discovery so much as an idea that I spent hours trying to actually implement :P
