Someone commented on your recent YouTube short...
"It would be so cool that zombies get more active during the night, so we feel safe to stay inside the houses during that time, but we can hear the sounds of the death outside. That would be awesome!! So we should be able to play cards and indoor games inside with our friends trying to be quiet."
This would be a great implementation, especially the more active zombies and the sounds of death more apparent with the activity at night.
