I liked your take on mining, bringing up a little mini game was a neat idea. I had some trouble closing interactions which ultimately kept me from finishing the game. The only way I could figure out to close interactions was using esc but that also brings up the pause menu, so it got tiresome having to close pause every time. There did not seem like a working way to close the inventory so I would have to exit to main menu and reload the save.
The game looks really good, and the sound design and mechanics are great! I would like to play this all the way through sometime if I could figure out how to get past the small problems I faced.
