I wish there was an option to have the camera controls not inverted. It was really hard to get used to the inverted camera controls. I think the delay in the camera movement was too high for me to get the grasp of the inverted camera controls.
When I tried to use WASD to move, I felt like it wasn't doing anything. A short and easy tutorial would be nice to teach me how to pilot the ship. I had no idea where I was supposed to go.
Other than that, you did a great job in making me feel like I was in a space ship in the middle of nowhere. I love the music.
