Great start!  The enemies were tough.  

Good Job. I found myself playing several rounds to get used to the enemy speed, and tank controls. I felt a nice sense of achievement when I started to last more than a few seconds :D  I found that if I caught an enemy at the edge of my flashlight they wouldn't disappear, it might be worth extending the collision area (or reducing the flashlight length).

Great work! I love the atmosphere the flashlight gives it, coupled with the high enemy speed it brings a lot of frantic tension. It would be great to add a couple of HP/Lives, so you can survive a few hits before dying.

This is very well done, I'd not have even dreamed of coding a flashlight when I was that age.
