Nonozle

A picross game that really has everything you'd want! It plays especially well on controller, if you have a good d-pad, and the randomly generated levels are a good thing to go for once you beat the long list of pre-designed levels

If you've never played this type of game before and are unfamiliar with nonograms/picross, there's a few free ones on Steam like Picross Touch and Picross for a Cause. You might consider trying those first to make sure you like this style of puzzle.
If you are familiar with nonograms/picross and enjoy that type of puzzle, then you'll probably love this game. All the standard quality of life features are present along with a bunch of fun options. It took me ~38 hours to complete, so it's a good amount of content. There's no DLC achievements.
Some of the puzzles are called 'abstract' which just means they don't reveal a picture like standard picross puzzles. I'm not really bothered by that, but it bears consideration if that's something you value in a picross puzzle.
I'm a huge picross fan. I don't have any complaints about this game. The difficulty was perfect and the controls were great. The price is very reasonable for the amount of playtime you get. Plus, there's workshop support and a randomized puzzle mode. Excellent game.

Awesome game. Dev clearly went above and beyond in customization and QOL features. Just super fun and chill

Very fun and straightforward nonogram game. With 300 handmade puzzles and infinite random puzzles after that. I enjoyed every minute and often come back to it for a new puzzle or two.

I enjoyed this game rather a lot, and with 30 hours of gameplay it's easily worth the $5.95 price.
The game's focus is more on puzzles than pictures, and one of the two puzzle "packs" has no picture at all. The "abstract" puzzle pack is just a number puzzle, with no picture formed. It is particularly challenging, and I enjoyed it a lot.
- Game doesn't punish you for mistakes, or warn you about them. There is a handy button to check that the board is correct, and an undo & redo button. Without these features the larger abstract puzzles may have been too difficult for me!
- There are MANY settings options, and I highly recommend looking at these early in the game. There were some settings there that I would have liked to have turned on, but I didn't think to go searching through all of the menus and sub-menus.
- No glitches or technical difficulties.

Excellent Nonogram game! Minimal look, but with lots of customization options, Steam Workshop support and several quality of life features! Absolutely worth buying!

Game has a soundtrack with so much emotion than most of AAA games released in recent years
