This is the first Picross title I've ever played, but definitely not the last one.
While I enjoy all kinds of puzzle titles, I'm exceptionally keen on the ones that require some kind of algorithmic thinking in order to solve them (like sudoku puzzles).
Picross filled this itch inside of me. The basic rules are really simple to learn, and once you solve a couple puzzles, you will get all the necessary tools that are needed to solve even hard ones.
For this price, the amount of content you get is just unbeatable!
