Really impressive game, and really ambitious project for such a short jam.
It was a bit confusing though, like what was the point of selling your stuff? there didn't seem to be anything you could do with the currency. Also the Re-fueling system could use some balancing. I found myself mining only fuel, just to get enough fuel to find even more fuel until I ran out ':D. Or maybe I just missed something important, that's possible too.
Nonetheless really impressive project. :)
