would love it if there was a category to speedrun all the puzzles instead of just clip

This is not a bad idea...

I've set up this leaderboard to follow categories of other Picross S games. It should be more coherent to have this category in every Picross S leaderboards, but I do not have permissions to do that for Picross S1 to S4...

If you can achieve an "All Levels" run, I will add this category at least for this game, and talk to others mods to do the same on their leaderboards.
