This is one of the only hacks I'm really interested in playing. I downloaded the beta and all I can say is, "wow". Azure Horizons does not disappoint.
While playing, I found a few errors:
You can walk on the flower pot in the player's room.
Some movement permissions are missing in the player's house.
It's possible to avoid the grassy patch there by walking through the ledge.
The player is blocked to his right. The wrong movement permission is used.
As you can see, Gordian Town is highlighted. While looking at the Town Map in Gordian town, the player appears on the far right side of the map.
