I have a very new suggestion.
I've seen some life survival liek games and this one seems to be missing something in the middle.
For example, we have low level fists, and high level swords.
What about in the middle?
Like a bone dagger of some sort.
You use a boar tusk or maybe a carved bone, with some bough, and a woodened handle, you can make a bone dagger for fighting or defense?
There could also be a new skill.
Also, I suggest that we can have maybe a crafting items like chisel and such to make better items.
Like you can use the chisel to craft some items that a stone axe or maybe your hands won't be able to craft.
This coudl open alot of new ways like crafting tables, new decorations, sculptures etc.etc..etc
