Loses some points because (on 3ds at least) the battle system mostly feels like a detriment to it (I tired of it pretty quickly, even after figuring out pretty workable strategies for a team composition I cobbled together) and two worlds of content are locked behind a now-defunct and/or JPN exclusive account system. But other than that, it's a good compilation of Picross puzzles, paced well enough in difficulty to stay compelling. I now understand and almost enjoy Mega Picross, which I always struggled with in the past.
