@peterdrake It's a cross between the old classic Asteroids arcade game and a modern miner/upgrader.
You have to venture out into the rings, find rocks with minerals, break them apart, and then gather the minerals in your hold (while dealing with the physics of big heavy rocks bouncing around inside you). Then you return to the station to sell and repair and upgrade and repeat.
It's been a while since I played it, but if I recall, right is deeper into the rings and left is shallower. Go far enough left, and it'll prompt you to autodock to the station.
@LouisIngenthron I don't get the appeal of mining. Maybe it's just not my genre.
