New examples and bug fixes.
Your example of the Plumber puzzle game is terrible, I was defeated many times and it traumatized my psyche.
My grandfather was a respected plumber, just like my father, and it's sad to see how you could create such a terrible illustration of the logic of plumbing.
If you do not correct this example within 76 hours, I will complain to the National Union of Plumbers of Kazakhstan.
I'm very upset right now....
