is there any way to romance min and get everyone to believe in the prophecy? or am i being a bit dumb

I played the web version at Choiceofgames' website and it ended at Chapter 4. How many chapters is the full game?

I can't help but feel that there should have been an achievement for being an honest, humble illusionist who deceived the world into believing that they saved the world, like my first playthrough. Why isn't that an achievement?
