And here is something relatively complete. I've finished implementing custom puzzles for my nonogram game! The game now comes in its own folder to accommodate the custom puzzle files, and includes a few of them for you to try! The code itself is about 1000 lines long and a complete mess. You can still look around in it if you want. Feel free to learn from it, etc.

As always any feedback, suggestion, bug report, etc., is much appreciated! I might make custom puzzle packs every once in a while. Who knows... it might give you something to do. :L Also, if the key isn't clear enough in the screenshot, it's «7K43X4ZX».
