Interesting idea, here some hints for improvement:

-the main source of light should be the star itself and not the universe. Currently the ships get their environment light from outer space, than from the star itself
-maybe add some kind of central station, for at least some minimal cover
-when the camera origin is below the surface of the star, the game stops rendering the scene until the origin of camera is out of star again
-maybe you can add some extra outer shells to the star, which are non solid, like the snow on Pillars, when moving into the outer shell, your ships should maybe get some buffs/debuffs (maybe disabling radar and comm of the ship, but enemy is also not able to detect the ship with radar

A central protuberance would be cool. Something that kills ships and destroys shells and missiles, but does not stop radar and comms.
