To someone who likes picross in general and plays it casually while listening to podcasts, songs or other forms of media, there's no denying that this game is more of that at a reasonably low price.
That being said, there's not much else outside of it. Its art style appears to be a re-skin of other titles from the same publisher, changing it according...
The interface is only passable, the system for crossing out blocks is buggy, and it doesn't have "no, seriously, don't give me *any* hints" mode (i.e. do not tell me if I make a mistake), but the puzzles are for the most part good and it's certainly cheap enough.
If you've played through the good free ones like https://www.kongregate.com/games/BeardshakerGames/nonosparks-the-ark...
Best Picross game so far (haven't played any other picross games).
Aside from the same problems I've noted in reviews of other 8Floor picross (paint-by-number) games (inability to look at completed puzzles and unforgiving interface), I've just noticed that these games take way too many clicks to exit the game.
