I played that demo. It is very good. The AI is the most impressive part. The characters are outstanding as well. The inventory works very fine. The scripts must be superior.

Here a few critics: The corridors in the dungeon are looking all the same. So I cannot get orientation without the compass. There could be more entities and different designs. Light is coming from stones without a hole in it. I have my problems with the fighting system but that might be okay for other people.
