Nicely done!
Some random thoughts:
- The controls feel very much in line with one of the best spaceship games I've ever played, "Freelancer". It's an oldie, and weirdly enough doesn't seem to on steam or gog, but worth a look for extra inspiration :D.
- I had a weird issue in which the space stations would disappear if I went a bit far from them to try to make a U-turn and come back. I kept looking for them, but I couldn't see them, not sure if I was just being dumb though.
- I wasn't very sure what exactly I had to shoot at. May be having a small sound effect that triggers when you hit something that can be damaged may help?
This is a fun game, nicely done!
