I liked this! Great aesthetics, I really enjoyed walking into the ship everytime, i think that transition works well and creates a great sense of safe haven. I think you should expand on this and it could be really cool.
A bit of background music would be awesome, and I would have loved more visual indication of how far the rocks are along to breaking, as initially I wasn't even sure I was doing the right thing with the drill.
Movement in space doesn't quite feel fun exactly - it could do with a little tweaking I think to feel more skillful than slow and frustrating, especially with rocks flying away from you as you drill.
The quest system was really cool and you had some nice writing in the game! I'd love to see other threats out in space. There's a lot here, and I think it's an awesome take on the theme.
