I don't get it either
I liked the fact that you had to interact with this to advance,
but I have no earthly clue as to the point you were trying to make with this.
suggestions:
try to indicate that you can interact with this movie in the beggining somehow. I shot some guy in the head by unexpectedly.
I think I would have thought that the beggining scene was alll that your movie was.
try to have choices instead of straight foward advancement, it would make i t more interesting.
