Day 330:
I did manage to shore up the chamber I mentioned yesterday, so now I can go through a heavy set of wooden doors and drop a support beam behind them if I think something’s chasing me.
This has been very effective against the zombies, but the exploding giraffe-corgis still sneak up on me and explode on a regular basis. Do not like. Head hurty.
I also dug out a much smaller second chamber. Ok, actually what happened was that while I was pulling ore out of the big chamber on my way to sheep Nirvana, I followed a vein that, when I was done, was essentially a chamber in and of itself and just needed the walls to be shored up a bit.
It’s a good thing I did so, because as I got to the back of it, I discovered it opened to the outside world — not cleanly, but in a “hey zombies can fall in this hole and kill you” kind of way.
So that’s secured as well.
