Demo v0.21.0
I think it's the biggest feature since addition of food and can change core gameplay loop
Barter NPCs
Now after upgrading area twice the NPC will spawn. Each area has it's own unique NPC:
Forest:
Limestone:
Hardwood forest:
Sandstone desert:
Each of them mine their own resources, depnding on area they are in. And after they finish you can trade their resources for lower tier ones. Softwood logs for sticks, limestone for softwood, hardwood for limestone and sandstone for hardwood. Ratio is tweaked to be more profitable for player, but the tier of resource still counts.
After trading several times NPC will level up and will provide both better and bigger trade offers. This could help with both automatization and with utilizing lower tier resources, which ended up being completely useless at some moment of the game.
Side effects
Adding objects earlier on areas upgrading allowed to unlock other things earlier. So I made skill workbenches and woodpecker birdhouse unlocked after the first upgrade of areas, since I noticed that some players didn't upgrade areas enough to reach these things. Now since all more content will be available eariler I hope less content will go unnoticed
