[LVL 4+ Train] Crap games, but lots of copies (140 keys)

Since my last craptacular train was mostly successful, here's a follow-up. Lowered the level requirement to 4, but made a more engaging puzzle.

I'm partial to Nonograms (aka Picross, Pic-a-Pix, Pixel Puzzle, Griddler, or Hanjie) so I made my own! If you don't know how to solve these puzzles, the wiki page does a good job of explaining. Know that a real Nonogram ends up with a neat picture, especially the bigger ones. Mine... not so much, but at least it introduces you to these fun puzzles.

Here is the puzzle.
