I found 12 Word Searches on reddit yesterday, and I have not been able to stop thinking it about it since. I finally just solved it after a few hours and enjoyed it a lot. I loved the "oh shit this is getting serious" feeling after naively solving the first 11 puzzles. The last times I had that feeling was when I played Outer Wilds and Subnautica.
My favorite part was definitely finding the second "zodiac" in the 11th puzzle. I had already finished the 2nd puzzle and I was searching for "animal". I searched for it way longer than I care to admit. The grand finale with "as now you have won" present twice in puzzle 12 (present once normally and once as leftovers) is also a high point.
