This is likely to be a shock to every fan of the series. It may also not be fully representative, as the number of files purged by the game on HowLongToBeat is small. But, given the length of its predecessor, it's worth keeping.

Mario's Picross 2 is another Picross game. The player uses logic and numbers to uncover various images, except that Mario is there looking at you. It's portable and has a lot of puzzles to play with. It's a game that would make any long bus trip disappear into thin air, and it's a shame the game never officially made it to the West. It's just a fun puzzle game.
