Picross S2 is another letdown of a game in the Picross series, but that's no surprise. It's an acceptable game (and having co-op play is always a nice bonus), but just... ugh.
The worst is that S2 added "clip mode" or whatever, so instead of just solving puzzles that look like something, you get... tiny, random-shape puzzles that don't really resemble anything, because they're all part of some larger picture. Except the pictures aren't very interesting, the puzzles are pretty bad (because they're not made to stand on their own), and just. bad. not good
It doesn't help that the game only reaches maximum-size puzzles (a pathetic 20×15) at the
very last page, staying with "even the GBC could do this" 15×15.
And of course, Mega Picross is just the same 150 puzzles as normal mode, but with different 'mega' hints. Boring.
The sad thing is that there's a Kemono Friends variant of Picross, and while it's the same engine, they at least added a shred of life to it with the animated characters and theming...
