It's incredible that this three hour game has procedural generation in it! I agree with the other comments, in particular the one about having an upgrade that increases the area you can mine, so I'll just say that I very much enjoyed my time with the game.
I almost completed it, but unfortunately came across a crash at the very end, and again about a minute into a new game I tried. I wonder if it has something to do with how quickly I was mining? I was holding down my mouse button and traveling in a straight line. Hope you're able to figure it out!
