Will there be more player characters in the future or just the current two?
The current two are good, just asking because of the DnD theme.
The DnD theme lends itself to many more ideas for characters, enemies or events :P If the full game sells well with these two, I could definitely see a future with sequels involving other classes in different dungeon environments (ex : Archer and Druid in a forest, Thief and Priestess in an underground city, etc.)
