This is just a demo, so yes, there are only two dungeons available on the demo, and there are also a few features that are missing. Currently I'm working on the full version of the game, which will include 12 dungeons in total, along with some other features.
Ok I wanted to make sure. I wish you good luck on your work then. I had a blast with the demo version. I really appreciate the races/classes choices ; it adds a lot to the replay value.
