This was a pretty well-rounded game, though it was notably lacking in some kind of feedback to let me know how far I had made it. Any kind of progress meter - distance, points, etc, would have greatly added to replayability.
The ammo was also a bit too generous. I always gained far, far more than I needed.
I think the coolest part was the zoom-in effect during sustained fire. I felt it mimicked the real-world effect of "target fixation" and was the primary cause of my deaths in the game. Great work!
