its not a game
Maybe its just my personal opinion but i cant give you a high score for this because this is not a game it is more like a project and i believe that you dont even care about the score anyway you just wanted to show your skills.
Im not a developer so i have no idea how hard it is to do what you did but something that amazed me is that i was moving around in your project and i got dizzy wich is very uncommon for me. I had never got dizzy from any game or movement from a virtual camera before. Good work :D
