Nice starting point. There's a lot I can see didn't get done that you were planning, like the timer and kill count. Also, a way to exit the game other than making it windowed would be nice. I pressed Alt+Enter to make it fullscreen before I realized you didn't have it, and had to use task manager to close it when I was done. I'm guessing you didn't have a lot of free time to work on this, but what you had so far was pretty decent. I'd love to see what you can add to this once you have some more free time on your hands! For what it was, good job!
