I liked the concept a lot. I think it has a lot of potential! If the HUDs were larger that would help. Also matching up what you mined with which to send back was hard, I just ended up pressing on the arrows until it no longer took any more. Being on the moon some physics to make the weight on the drilling machine less would be cool. I think you have a solid concept, I would be interested to see where it goes if you continue working on it. The music fit the atmosphere of the game really well!
