The presentation on this game is fantastic, and I was really impressed with the intro & ending cutscenes!
I would say that the ship could do with having its base movement speed increased slightly, as at first I thought I needed to hold down the left mouse button to move. However, it did help to sell the feeling of the ship being a large capital ship rather than a fighter, so I can see why you went with it - I think maybe it just needed more of a visual indication of movement, such as more of a thruster effect from the engines.
The combat was well done, I liked the more hands-off approach of the guns auto-firing - great job!
