Really incredible puzzle can't believe how smoothly it solves! Until a huge wall I hit in the middle that I think deserves a 3.5-4 star rating. Really lovely!

Great puzzle. Interestingly, for me, chasing down the shaded cells ended up being far easier than resolving them. Lots of narrowing down and then clicks into place. Enjoyed this a lot!
