Hello, i just came across an idea that in my opinion would improve the game, what do you think about upgrades?
For example you have just built your little wooden base got a steel door but the walls are still destructible am i right?
So how about if you have enough metal then you can create metal plates and nails, then using that you can somehow upgrade the walls to metal plated walls.
This is just a quick suggestion.

Oh i also have an idea to implement a better system of leather so when you kill an animal you get pelt then you can transform it to hide and finally into leather. Animal pelts could be used for the bed roll maybe and leather for something like leather armor i don't know this is just my suggestion. Tell me what you guys think ;)
