My first criticism is that the main ship takes up way too much screen retail. It's so much of the playing field that it becomes impossible to spot enemy ships. While a radar would make them more visible, there'd still be so much less visual confirmation that you're shooting your target and it runs into the same problem some space shooters do. I don't want to shoot at magnifying glasses on the edge of the screen, I want to see my shots travel from my ship to theirs.
Zoom out that view of the playing field enough where I can see other ships within shooting distance. By default. I didn't even see in the directions that one could zoom out, but zoomed in is rather worthless. Once I zoomed out all the way, it felt a lot better.
