Got a score of 9762 at my first try! I like it quite a lot but I got confused with the keys a few times. It might be good to display the key on the space ships.
I also prefer to use the keys s, d, f, j, k, l, instead. Not sure if this works better.

Yes SDF JKL is a good layout too, although it makes it more difficult to change how you move your hands as you have 2 separate areas. As of displaying the keys on the spaceships, well, with only so few pixels available, that would make a lot of noise on the screen. But a compromise would be to be able to display it by holding another key I guess.
