I’ve done enough of these picross games now to know there’s very little to say about them. For the most part, for the Jupiter developed ones (like this) at least, they’re pretty much the same.
The different thing in this is “clip picross” mode, where parts of a larger puzzle are unlocked as you play through the other puzzles, and then you complete these parts to make up a larger picture. It’s a bit like in previous games but instead of each puzzle in the clip puzzle being made up from the same size puzzles, they’re all sorts of different multiple-of-five sizes.
In all, I’ve spent probably 25 hours on the game, so it’s definitely value for money, as always.
