So in my one file in Alpha, I am currently working on two major mining projects. I will keep track of my progress here, for you, the loyal interested readers.
One is a 15x15 mine shaft, and the other is a smaller 10x5 mine shaft that I just drew up on a tiny island that just generated near my spawn chunk.
I am in the process of recording images for a time-lapse compilation, which should be pretty sweet once it's done. Look for it here sometime in the future!
