Love me picross, simple as. Compared to the other PC picross games I've played it has the best controls, not much to say other than that. I did a majority of the puzzles but kinda lost steam once I hit the 30x30 section. They always just take too long to do so it's not as satisfying and it can be really disheartening if you get 20 minutes into a 30x30 and realize you marked a wrong spot somewhere.
