Really cool! I liked the usage of shaders, loved how the stuff really gets into the high gear when the alarm starts.
Most of all- I'd REALLY like to play the game that starts this way!
Only one criticism- the cuts at the start (before the alarm) come maybe a bit too fast? I'd let those takes linger a bit longer, to contrast the action, when the alarm goes off!
Other than that- one of my favorites!
