I like the whole stone tree idea, but currently it is kind of difficult to switch from hatchet to pickax. Also, you do need wood to craft metals, but Zack0 rejected the idea of charcoal when we suggested it, because it would be a waste of time to craft or something.
Yes, but it would be easier to code that than to make it take "any wood" in the smelting recipes.
Seems stuffty that you
have to smelt Bronze with Oak wood, and higher grade metals with higher grade wood. Wood's wood, two oak logs should do just as well as a willow in the current system.
As to swapping between tools, hopefully in the equipment system he'll be making it so that your current selected weapons go in your tools (I'd say two slots would be fine for that)
