Very fun puzzle, well constructed logic! Oddly, even though my solving time indicate a 2*, the deductions felt like 3* to me.

Thank you for your comment, galium_odoratum! I am glad that you liked the puzzle. Considering difficulty: I also thought it might be 3*, but I am happy to hear that many found it more approachable.
Kind regards, sujoyku
