There's not much to do here besides watch, I guess if you really wanted you could change your speed. It was a cool design idea I had one time and I decided to make it a thing, and it came out pretty decent. You can get a high score by watching for a while. Space to show important variables and reset clones button (which you will need to press after you change the clone multiplier, so it can go into effect) Turbo Mode is recommended for realistic looking speeds. (although all it does is make the stars move faster)
Thank you Star Trek for inspiration.
