herds of zombies will spawn in large numbers around the player at night
(radius, range, and amounts can be edited in the config)
these zombies will only spawn in spots that have a light level bellow 6 (this can be configured as well)
killing zombies will make you go insane (insanity meter will appear as a bossbar once the player has entered or is in the target world which must be set in the config)
sanity will recover over time the recovery amount can be configured
eating rotten flesh will impact your sanity significantly
