A couple notes. – Mine Upgrade Review

With a little investment the game plays itself, which holds to the genre. But I cannot just let it sit while I forget about it for too long. Which is good and bad I guess. A few things: 1. I just got an "Artifact", like a gemstone I'm guessing but the flavor text was gold. I found it after mining Limestone for a bit, I have no idea what it does or where to find it. 2. If you purchase a new workshop and then purchase a new unit, you get a unit for each workshop you have ( I have 3 forklifts, 3 spike balls, 3 cars.) I don't know that it was intended to be this way but I've been exploiting it.
