I don't understand movement: "W" makes me appear to move backwards, "S" makes me appear to move forwards. When I use space to stop, I move back to where I started.
When you speed up at speeds comparable to that of light, the angles, amounts, and wavelengths of light which reach you will change. This means you can't visually judge brightness, color, distance, and length the same as you normally would.
E.g. when you accelerate ("W") the angle the light rays from in front of you appear to be coming changes, making them look farther away. If you let go of "W" you should keep your current velocity and see you are indeed still moving forward, just in a world more pronouncedly warped by the effects of relativity.
Is this a bug or am I just really confused?
