Loved it. The coloring, the idea, box one, the pointing cage, and disambiguating final colors using all the clues and sudoku logic. Thanks!

Wow, what a treat! Nice break-in and then very, very smooth solution path. (If you don't mix up your colors...)

Very nice puzzle! I love your setting style @NicoD. In some of your 3* puzzles I get stuck somewhere in the middle, the more satisfying it is when I manage to solve one. Thanks a lot for creating and sharing.

Super fun coloring exercise. The constraints are really interesting and the solve has some fun challenges throughout.
