Add:
Night events into a different mod maybe.
Darkwood implemented them very well

Change:
ghosts to have a counter (block, item or something to keep them away)
ghosts doing damage maybe make them not deal damage and instead be support (throw slowness and snowballs to annoy you (debuffs should be configurable).
entire mod should pause if player loading the chunks is afk to keep mob farms functional
Increase screech sound volume enough that you can hear it from deep underground (BNW2 ground is 128 blocks deep)

No longer maintaining 1.16.5 branch, closing
