I had fun, but in respectful honesty it's got a little ways to go.
At one point, one of the enemies seemed to become completely invincible and I'm not sure why; I hit it with my entire reserve of salt and it didn't go down. The key is non-intuitive (I kept trying to figure out how to pick it up). Also, a fallback weapon would be very handy for when we run out of ammo!
Otherwise, solid game and thanks for contributing!
