Nice! About 2* difficulty until you get the low digits sorted out, then a solid 3* with high digits.

Amazing, I normally don't go much for killer puzzles, but after seeing your name I had to try... And I don't regret it ! I am so glad to see you posting new puzzle this year :D

Very nice but hard colouring puzzle - 82 minutes!
I don’t manage to solve many of Florian’s puzzles so this seems quite an achievement for me.
