I just finished v1.25! Thank you! From my texts with a friend, it took me exactly 30 minutes to figure out I needed “AS” in the final message. Oops! Afterwards I did go watch Icely Puzzles video on your book and I do like the updated 12th :) I like the omega theme too.
Personally I needed 0Rules. I “solved” 1-11 in order without looking at ANY of the meta puzzles. I did mark some palindromes but didn’t make the connection with any metapuzzles. I really had to study the bottom left a-z0-9 on the 0th puzzle to understand how it works for everything else.
Here’s a photo of my completed 12! https://imgur.com/a/NF38UOd
