This was a fun variation, thanks!
This whole week has been an enjoyable introduction to Nanro (for me).
Really loved this variant!
One of the most impressive constructions of an outside-style puzzle. Be sure to account for all clues (I forgot about one of them for awhile).
Thanks, folks! I’m glad you all enjoyed this one.
Over 3 years had passed since I had originally created this one, so I got to enjoy it as well since I was basically solving from scratch without much memory of how things worked.
