The grand-ultimate Picross game on Steam.

A whopping total of ~350 puzzles (plus workshop support) that range from trivial 5x5 to the hardest 40x40 I've played on the platform (took me 90 hours to full completion). A lot of options to tailor the game to your liking, from theme selection to gameplay/controls tweaks. Secret easter eggs and achievements even. Look no further because this game has it all. And if you still crave for more then I recommend Paint it Back which does have comparably challenging puzzles, with Pepper's Puzzles coming as a close second.
