I would've liked to have been able to keep the policies open while filtering through emails, as I couldn't remember the rules easily :)

If it wasn't obvious, Papers Please influenced the design of this game quite a bit, and originally I'd wanted to have the rulebook be a physical thing that you could drag up from the bottom of the screen, but for time's sake I ended up with a UI element that conflicted with the email. For a future version, though, I think that would be a great goal to aim for.
