    Brilliant puzzle. It took me 35 minutes but it was worth to sacrifize this time to have this pleasure in looking for 11 liers. I marked every of them red, having satisfaction every time when I discovered one of this fooling clues

    Wow, this one felt very satisfying to solve! Great use of the ruleset, I had to use a lot of different application of those rules to reach the end, but never got stumped anywhere. Very smooth solve overall, this was my favorite puzzle this month.
