Special Thanks
Edit: I have been fortunate enough to receive a Cracking The Cryptic feature for this puzzle.
This puzzle was set for the weekly Scojo discord/twitch prompt, where the theme was to use constraints with the colour of the discord flag you chose, which for me happened to be green. I had a play with German Whispers and Shifters, but didn't find any new logic that I liked and then I remembered an old puzzle of mine...
This puzzle reuses a constraint that me and palpot used on the Halloween Special Dutch Flat Mates, which fittingly was also set for a Scojo weekly prompt.
Initial Setter Difficulty: 3 / 5
Normal Sudoku rules apply
Place the digits 1-9 so that they do not repeat in any row, column, or 3x3 box.
Zombie Cages
Digits in cages must sum to the number in the initial top-left corner, and digits cannot repeat within a cage.
ALL cages must grow by at least one orthogonally connected cell (could be more than one!).
Different cages cannot share cells.
Hint to start
There are nine cages with totals that must include a 1, there is tension in where those 1s can be placed.
Solution code: Digits from Row 3

What a treat! Thanks :)
I usually do easier puzzles (1*-2*) and this felt pretty easy to me. Just took me 41:17 because of some failed basic math along the way..

This was the first time I encountered the Zombie Cage constraint and I have to say this puzzle was quite lovely with very enjoyable logic.
Thank you Flinty!

Nice puzzle, but I'd say more or a 2* than 3*.
Flinty: Thank you, I can appreciate that it would feel like a 2/5 if you spot stuff quickly. Good job. :)
