About the same as the other picross games from Jupiter. I don't really understand why there is no drawback to making mistakes.

It's picross, and there are many, many different puzzles to choose from. I like the variety between regular puzzles, color puzzles, mosaic puzzles etc. It doesn't make me want to watch the anime (?) it is based on however, and sometimes the puzzles reveal images that mean nothing to me as a non-viewer. But the core gameplay is satisfying and there. Maybe one day I will finish all the puzzles.

All puzzles solved with all medals
