And it was a 3 star for me. Took three resets before I solved it. Great telegraphing once I knew what to look for.

Some nice interactions in this puzzle, thanks! For me it's quite harder than 2* at the end.

Welcome back Ridhwan...thanks for sharing a very nice killer puzzle. More of a 1* for me, others might find it a 2*.
