The ship looks nice, and so does the particle trail. However on my machine the ship rotates way too fast. Make sure you're using Time.deltaTime or clamping the rotational force so that you have the same rotation at 15 fps vs 300 fps. Also it doesn't feel like there's an inherent threat in the meteors, maybe make them move faster. If you continue working on this I think it can be way more fun than it already is!
