Fun game if you like Minesweeper. (It's a lot less Picross and a lot more Minesweeper - it's forming one large picture, but that's about where the Picross ends. It fully follows Minesweeper rules.)
It's been interesting to learn about various 500 year old Dutch proverbs, and after the 50% completion mark I started to pick the game back up every spare moment I got.

That said, one minor gripe: when you use the button to clear errors, two undesirable things happen:
1) The erased tiles dramatically overshoot the actual mistaken tiles, and erase a larger chunk including correct tiles; this includes even deleting red tiles placed around 0s.
2) On both Steamdeck and keyboard/mouse on PC, pressing that button both clears tiles and makes the game think you're clicking through it to whatever's under it, so if that button is hovering over a completed proverb region, you get that proverb as a popup again.

(Also, beware of overusing right trackpad controls on Steamdeck with this one. It's a satisfying way to play, but it flared up my old De Quervain's tenosynovitis.)

Overall, I do recommend it.
