I'm not very good at the game so I didn't get very far and only played on easy, but...
It's a great idea and well-implemented. It's aesthetically sound, if a little simple (but only having 48hrs to make it is a great excuse). Not exactly the most original idea, but it certainly does have the out-of-control feeling. Although, I think I would have liked to see the aliens laid out similar to the QWERTY keyboard and slowly shift around as the game progresses.
