My wife and I have just played through Episode 3, and we loved it! However, after reaching the end and winning every fight we could find, including Molly the Were-Zompire*, the classes we used for the whole game are only up to level 43. Are there fights we may have missed, or do we have to keep fighting Molly (or other Colosseum battles) to reach maximum level? I want to see what happens in the temple when we do! Do you get more experience on Insane difficulty, perhaps?
*Fun fact -- FireFox spell check thinks the "Zompire" isn't a real word for some reason.
