I think my judgement was somewhat out as I worked backwards for the main part, doing the harder puzzles first. Which meant that even though I’d only done about a quarter of the picrosses (picrii?), I’d spent two thirds of the time on them.
Not that any of this is interesting, I just thought I’d mention it. After all, there’s not much to say about a Picross game, especially after four iterations.
e5 soon please?
