    I found this much easier than I expected from the star rating, and this is coming from someone who generally struggles with the harder puzzles on this site. I really enjoyed the solve – lots of fun principles.

    Gotta say, I’m disappointed to see that Grant’s twitter is so much more toxic than it was six years ago. Instead of solving this one I’m donating to my local community bail fund.

    I have become aware of an organization with a Small Business Relief Fund to help rebuild small black-owned businesses in Chicago which have been decimated by rioters and looters:

    I don’t know if this will be enough to make you want to solve my puzzles again, but I have requested that all the money I would be owed for a puzzle ebook that’s currently in the works be donated to this organization’s Small Business Relief Fund. Have a nice day! 🙂

    This was meant as a reply to Jonah, but WordPress is confusing. Oh well.
