Thank you for the feedback.
Collision is among the things I've been struggling with so thank you for the suggestion. Missiles will get some more work. During my own testing I noticed a lot of problems but I had more immediate things to tackle for the demo. The enemy ships actually have trail renderers but maybe they're too short.
The thing with rolling is actually it is rolling around the ships center but the camera responds so aggressively that it looks like it doesn't. I'll take a look if I can adjust it.
