I just finished this and really enjoyed it! Excellently done! I had seen it recommended by Board Game Blitz on Youtube. I did version 1.23 on paper.
I found puzzle #1 to be the hardest part. After I tried to do all the crosswords, and went back and changed my answers on them after realizing the words could bend etc, I used puzzle #12 to help me figure out what the leftovers were on the puzzles I hadn't finished yet. Then after getting the final message, I didn't trust that I was actually done lol because I had no idea what the letters and numbers at the bottoms of the pages were and assumed they were an additional puzzle to do after the word searches. I came here to find out how to use those clues, and I used them along with like four lists of cookie types to finally finish word search #1 haha!
Anyway that was really fun and I didn't want to put it down to go to bed last night! Great work!
