Absolutely recommend this game if you enjoy nonograms (Picross), and even if you don't. The game has a criminally low price for the features and number of puzzles it provides, a cheap DLC adding a ton more, a random puzzle generator within the game so if you enjoy abstract nonograms you'll never get bored, and workshop support (!!!!!!) to play puzzles other users create.
There are so many settings to accommodate all sorts of play styles. It has multiple forms of assist including checking if the puzzle is correct (that doesn't spoil to you which specific square is wrong), a line assist to highlight rows that can have at least one square solved (without spoiling the specific square), placeholders for both squares and crosses (and buttons to either clear or replace all placeholders), and even a setting to disable all assists including placeholders if you really want to challenge yourself.
There's also a ton of settings for things like the theme (including allowing custom solid-color themes), what music plays, controls in menus vs in puzzles, lots of graphics settings, and some accessibility settings as well.
The music does become somewhat repetitive after 100 hours, but is overall very enjoyable and relaxing.
The game also appears very stable and I personally have experienced no crashes or bugs of any kind, which is always well appreciated.
Overall Nonozle answers literally every desire I've ever had for a nonogram game and there's a reason it managed to enter my 2nd most played game this year in under ~2 months. Imo, considering the popularity of the Picross franchise, this game is criminally underrated and really deserves more support, which is why I decided to write a review.
