Interesting concept but couple things aren't clear for me:
1. Who is the bad guy here? White lady or villa owner or both?
2. How does player actually solve White Lady's murder? only by collecting her body parts? I think there should be more.
3. Is the main gameplay similar to FPS (shooting enemies etc) or first person walking simulator (no shooting but lots of walking and finding stuffs)?
4. Continuation of #1, what is the failed state of this game?
