It took me more than an hour, but very pleased with myself. Great one!

• Leo Termin says:

Phew, quite the workout but I finished it relatively smoothly (first attempt failed somewhere in about 2/3 of the way through the puzzle, but I fixed my mistake on the second attempt). Very good puzzle to finish out this Nurikabe week, and I’m very happy to see even more Nurikabe puzzles (and some fun variations!) on this site again, as it’s my favorite genre.
