As someone who enjoys Picross and still plays games on Vita regularly, this is a good one. $11.95 AUD (though I notice Pic-a-Pix Classic 1) is also available at the same price. By the description, it looks like that title has the warm-up 5x5 puzzles, so it's good that they don't feel the need to go over it again, they're assuming you played the first one.
I can avoid death by not having a life.
