CiniCross

Here is an excerpt from CiniCross's description on Steam:

CiniCross is a dark fantasy roguelite built around nonogram puzzles (also known as Griddlers). [also known as Picross - ed.]

Descend into a cursed dungeon where every puzzle solved brings you closer to powerful enemies, and greater rewards.

The deeper you go into the dungeon, the more complex the puzzles become. Solve procedurally generated nonograms of various grid sizes from 5x5 to 20x20. Risk grows with depth, but so do the rewards.

Each floor offers multiple paths, all leading to a deadly boss. Every boss has a unique power that forces you to adapt your strategy and rethink how you approach nonograms. Along the way, discover shops, campfires, and other locations to aid your journey.

Collect powerful artifacts and items that change how you play. Automatically fill columns, increase rewards, slow down time, and more. Combine their effects to create devastating synergies during your run.

Every mistake, every wasted second comes at a cost. Death is inevitable, but each run is a new opportunity. Start over, gather new treasures, refine your strategy, and manage your time carefully to go further than before.
