The game wasn't so good, but the movie was great
The first irrelevant complaint I have is how difficult the game is. It's just not very fun. If you decide to improve it (doubt it, since the movie was the more important part), I'd change the reload to a keyboard key, so you don't need to completely screw up your targetting just to reload.
I'd also make the play button for the movie more distinct from the game play button.
Still, the movie was very good. Congrats.
