It's Ace Attorney meets Picross. Go buy it. (It's also on Switch.)
If you need more convincing for some reason, I've finished one of the four cases, and I'm loving the heck out of it. You might expect the story to be some thin framework to serve up Picross puzzles, but the narrative is definitely the main draw here. Excellent writing, excellent art, excellent music, and some pretty standard Picross (which is excellent). The first case took something like 2-3 hours, and I expect they'll only get more complex from here. Looks like there are something like 80 unlockable puzzles in addition to the ones you'll encounter in the story. It's a heck of a value for the price; pick it up so this can become a series.
