Sharp visual style, good sense of speed and movement, solid controls...I had a good deal of fun with this. There were some audio glitches when I played it, especially when I got close to the other ships and lots of clips were playing, but that's a relatively minor issue.
I think controller support and some punchier sound effects could both help improve the feel of this game pretty substantially, but using the mouse for movement felt good to me as well.
Also: Barrel rolls would look super rad with the tracer effects you've got on the ship. :)
