Not currently supported by these lovely people
I have a Patreon: Patrons get their name on new Puzzle, get to see it early, and generally get to be involved. However, I'm not putting this out as a Patreon-supported puzzle, so my patrons don't get perks. Unless they want them.
I will restart the Patreon next year, and there will be a short series of new puzzles. Use Patreon to help me make more, and I'll put your name on the list.
Enjoy this? Support another!
