I thought it might be difficult. But fun!
This is exactly what makes a simple Caesar cipher fun; when the words just look right in a normal grammatical sense, so you need to revert to a bit of real cryptography theory to eke out the clues. I’m not patient enough to work on any real crypto theory like a multi-alphabet cypher (even though they are also technically “easy”), so I really enjoy these simple things to keep the mind sharp. I’ve been doing them since I was about 10 years old when I helped my dad with Games Magazine puzzles.
