1.5 hours over two attempts for me, but I usually don't solve above 1*, so I'm quite ok with that result. Beautiful puzzle, thanks for sharing.

This is one of those puzzles that twists the brain, but you trust the process, follow through and a Picasso (err... solution) appears :-D
Very nice

Thank you for this fun puzzle, NotSoMagnifique! I enjoyed all those interactions of the different constraints. The difficulty felt closer to two stars, so let us see where it lands. :)
