Good stuff if you like Picross. I especially liked the variant rules. I only wish there are some hand-made puzzles, or if there could be a way to make those.
Thanks for the reply. I think I should clarify myself. After playing it some more, the randomly generated puzzles actually plays quite well (especially for H). I think the only reason I missed hand-made puzzle in other picross game is just cuz it feels satisfying to see a little picture in the end.
