I absolutely adore the game. I love the maritime theme and especially the mermaid. Almost couldn't stop playing before I finished the main part.
I enjoyed that the nonograms aren't too big. The nonograms themselves are also different from other games. I can't quite get my head around why, but I found them more fun.
From time to time I would have liked a few more dialogs. E.g. at the empty aquariums in the museum.
I've already recommended the game to my friends.
Now I'm hoping for a sequel!
