Pretty interesting idea. It was a bit confusing at first. I noticed that the head of NPC models is bugged. I noticed that the game has a multiplayer mode but I didn't try it, though if it actually works then its really imrpessive that you managed to make it in one week. What kind of networking solution did you use?
About the main gameplay. I found the battle mechanic a bit confusing. Its pretty hard to detect lies or maybe I just missed something. Overall I liked the atmosphere of the game. Well done.
