Tips for not getting lost underground?
Once again I find myself lost in the passageways and caverns of a tunnel connected to a mine connected to a ravine connected to another mine. I was thinking for a while I'll be fine until a creeper explodes in my face and destroys my breadcrumbs for returning home.
I'm hoping that someone has a good quick strategy to finding your way home even if you get turned around a bit after an explosion or falling through a hole.
