Great stuff!!!
I never read the backstory, but the game was still pretty thrilling! I think it should be modified so that you can switch weapons while reloading. Running out of ammo with the shotgun at close range is MUCH worse than with the pistol, which makes the shotgun even less inviting. I got through 14 levels without knowing it was even there before, and now that I rely on it I don't last for 4.
Still, it's a really fun game. Nothing really flashy or sophisticated, but since when was that a crime?
