One of the most enjoyable nonograms I've done on this site so far. Gives you enough of a good start and then a good thinker to finish it off. Not obvious math but there were clues if you took a second look and think outside the box. Also the motif is adorable. Well done imari13!
I flew through the righthand section so easily I could barely click fast enough ... then everything screeched to a halt and I am STUCK. Going to take a break and come back to look at it with "fresh" eyes. Determined not to take a hint!
I ended up taking a hint, and I'm frustrated because I couldn't figure out the logic behind it. Ah well, this was a fascinatingly difficult puzzle, with a great image -- thanks!
I thought it would be a spider; the bubbles looked like eyes and it wasn't clear til the end that the fish weren't mandibles... the fact that another comment called the image "adorable" should have been a hint...
