How does scene mastery work? What is the highest score possible per scene? What is the max level of mastery possible?

Each time you play a scene, things such as taking a hint, time, difficulty, and combinations of items found all contribute to the score that you can earn in each scene. The more points that you earn per scene, the more trophies you will earn for that scene; the scene will become a little more challenging each time you reach a new trophy level. The highest total score possible is 2 million points.  You can earn up to 5 Mastery trophies in each scene.
