Dropping off ore at the station is really fun, I wasn't sure if the spinning things would block my ship or not. It could be a good challenge to make them solid to force the player to time their entrance to the station when there's a clear path, although that might be too frustrating. Another thought is to have the ship actually dock with the station for a second or two while the ore is unloaded, it might make for a good pause to let the player refocus on the game field and plan their next moves.
I did find the asteroids covering the station frustrating; I would calculate vectors that don't cross the station area when spawning asteroids and setting their velocity. Also when spawning asteroids it would be nice to have an idea of how large it will be; I got killed multiple times from being too close to the warning icon even though I felt I was a reasonable distance away.
Overall though I really love this concept and style! I would definitely play this more with the changes I mentioned, HOWEVER, understand that I'm not a professional game dev or tester and it's possible some or all of my ideas would make the game worse in some way. If you enjoy it that's honestly the most important part, so take my feedback with skepticism and keep making things you enjoy.
