How long did you play? The character progression is much more customizable than the demo. You can assign up to 2 classes (5 now but more coming) to a character (1 at start and another at level 5) and skills are tied to stat levels.
Character customization is on the To Do list.
We still have quite a bit we plan to add to the game and will do a post next week with some more details so hang in there with us!
