Yes. You can now interact with the NPCs in the buildings, i.e. you can talk to them, they can give you quests and items and the dialog options can depend on your former actions in the game.
I also enhanced the inventory GUI to support selling and buying of items and added an escape mode for outdoor npcs. If you hit them with a weapon and they aren't enemies, they'll try to flee from you. It's very basic, but i didn't want them to fight you (because i can't provide the proper animations and i would have to equip them with weapons etc.) but i also didn't like it if they don't react on an attack. The current solution is a cheap compromise that works well enough IMHO.
