Loved it. Simple ruleset. Elegant execution. I love when a puzzle almost seems a little impossible but the next step is just within reach.

Very enjoyable! This was similar to what I was going for with my Chimes puzzle in the CTC line pack - but much more approachable than that ended up being! Nicely done

Very nice puzzle. I do think 2 stars is accurate, maybe a bit less.
