This morning I've implemented "wandering with purpose". Adults wake up and go to the work factory that is closest to their home, while kids go to the closest school. They spend a part of their day there and then at the end of their school or job they wander around the town a bit before going back home. All in 90 secs...per day. This will put people very close together to catch Covid, but as the mayor you can shut down the schools and have kids do remote learning and you can close or limit the amount of people going to their job, but of course you aren't going to make any progress towards Halloween that way.
I'm starting to worry that the 31 day construct is going to make the model less effective because that second graph from yesterday. Everyone's could be sick at the end of the month and that won't be exciting for the player. The decrees should help, but jamming everyone into work and school will counter those too. We'll see...I guess that's the fun of this.
