This mod adds a little immersion to the opening stage of the game. Breaking logs with your hand no longer yields a drop. You'll need to make a hatchet before you can chop down a tree.
Rocks spawn at a moderate rate anywhere you can find stone or gravel, on steep terrain, or near bodies of water. Sticks now drop much more frequently from leaves. Pick up a rock and place it on top of a stick in your crafting table to make a hatchet. Now you can chop your trees and keep moving foward.
