FlipPix Art: Simple Pleasures

FlipPix Art: Simple Pleasures is a collection of Nonograms (a.k.a. Griddlers or Picross) -- picture puzzles where you fill up cells in a grid according to number hints at the side, in order to reveal an image. You can select multiple cells at once to be painted or eliminated, and the game warns you everytime you make a mistake. Each puzzles comes in 3 sizes: 5x5, 10x10 or 15x15. Finally, each solved puzzle reveals an object inside a big picture -- there are about a dozen puzzles per set, totaling almost 100 puzzles.
