A19 lookin' sweet! I myself am not seeing any A19 change or addition which makes me doubt if it's a good idea. This is the first alpha to feel like that for me. I'll miss food poisoning but I realize that food will be in the midway of development in A19, while still acceptable.
I wonder if the "Difficulty" option will one day be cut to Zombie HP and damage options, relegated to the "Advanced" tab. Then "Difficulty" could just change some settings in "Advanced" and make the gamestage progress faster. That'd make basic difficulty viable changes for people who don't want to dive in the advanced options and think about what fits to their game or doesn't, considering currently people sometimes talk about how the higher difficulties make the zombies huge bullet sponges. It'd also allow more customization for the advanced players (Zombie HP and damage)
