Possible issue found: may not actually be generating puzzles at the difficulty it's reading. We looked at a few different puzzles at different difficulty levels, and they look to be about the same (from easy to hard). So, we may explore other options as well. At the very least, we could use this one for just generation (not for figuring out difficulty and selecting values to take out).
