I don't see where the Minecraft comparisons are coming in. It involves digging blocks, yes, but it's not a creative mode, you're not building things, and it's not open world. It's an entertaining score-based game that's more akin to a rogue-like.
That said, I've seen two potential bugs so far. I picked up a mineral scanner and it didn't show anything, but on the same screen, I found two gems and some coal. I've also had cave-ins directly next to mining supports twice. Do mining supports simply make cave-ins less likely? In my experience playing the game, they absolutely do not provide complete safety next to them.
