Hello, really enjoyed the book. Very well made and a lot of fun to solve, I think I've completed it. I figured out vaguely what was happening when I did the palindrome puzzle, which I solved fully before moving on to 8. Then after seeing the word list in nine I figured out the flipped words trick and then i went back to solve all the previous ones (before ever seeing 11, so I thought the theme for 2 was just animals and struggled for a while). Only after solving 1 fully did I realize what the numbers at the bottom meant. Then I struggled on 11 for a while since i thought the 12 theme started with l when it actually starts with L and I had forgotten the A from 6. Also that trick in 1 is absolutely genius. Do the page numbers end up being used for anything, cause I've completed it but I didn't end up using them.
