The failure states seem quite harsh though when I'm trying to explore the paths. For example, while playing through the "How a Bill Becomes a Law" example, if I make the mistake of introducing the bill to the house before a committee, I get a warning "WHAT BILL ARE YOU INTRODUCING? What could you possibly be introducing?". The all caps part is a font choice, so it doesn't look like users could disable it which might scare some players. I would have expected a much calmer explanation of the problem.
The other thing I would have liked is an easy link to a study guide or external resources. I know the whole point is to learn by exploring the decision tree, but I would have liked to stop and read more about what a committee is, or to learn what a "rule" is that I'm assigning to a bill (I still don't know). It seems like it's easy to get a rough overview of a process, but not to dive deeper than that.
