Haven't seen any mods for this game yet. So I thought I would just make a quick and easy one to get it started (needs Unity Mod Manager)

This mod has sliders to alter various variables in the game.

1) Building Condition Decay Rate
2) Tree Regrowth Speed:
This speeds up the spawn timer for new trees, but new trees will still only spawn on season change
3) Storage Slot Capacity: 
Allows any storage building (huts, storage, granary etc) to store more per slot (requires you to reload the save for changes to take effect)
4) Trader Quantity Multiplier:
Trader will supply larger amounts of resources (doesn't affect the animals or tech)
Trader Cheat: Traders show all available resources/techs/animals to purchase everytime.
5) River bank renewal rate: 
Fish/Mud respawn rate
6) Task Speed Multiplier: 
Affects most tasks so they are completed faster (crafting, harvesting, milking, shearing, etc)
7) Harvest Output Multiplier: 
Spawn more resources when you harvest plants
8) Animal production speed: 
Animals renew milk/wool faster
9) Animal Output Multiplier: 
More resources on each milking/shearing
10) Mine resource multiplier: 
More resources spawn in the underground mines (only affects newly built mines)
11) Human walk/run speed
12) Nutrition/Hydration/Rest/Morale Decay Rates: 
Allows you to speed up/slow down the decay of these stats to suit your game
13) Age Selectors:
Allows you to pick at what age your villages will become Adults or turn Old.
***Warning, trying to play Lord of the Flies with all children will trigger a game over
14) Raid modifiers:
Force start an attack
Stop attacks from spawning
Adjust how many attackers show up
