I loved the graphics, it made the game feel very immersive, and the sound effects were good too! I think if you make the ship's movement less tied to the camera it could give the game a better feel, like have the ship start accelerating in one direction first and the camera could "catch up" to it, or look ahead in the direction it's going in after a while, etc.  at first I didn't realize the ship was moving when I was pressing WASD, then I realized that the space around the ship was moving. Once I got the hang of that, I liked the gameplay!
