Cool idea! I didn't make it very far in unfortunately, I think my computer has problems running the game at the right frame rate - the jetpack doesn't work at all on my computer, for example, and trying to add a pipe to the pipeline crashed the game for me. Also, I found that if you go down the chute with the pipes at the start, it sends you into an infinite void. It was also a little hard to tell when the robot was doing anything without animations to denote it - so I didn't really understand how mining worked for a while. I liked the dialogue at the start! I'm not sure if there were any other NPCs to talk to because I couldn't really get very far without the jetpack. But it seemed like an interesting setup to the world!
