This game is what I would have wanted when I first played Solar Winds (and later Escape Velocity).
Also considering everything else great about it, the combat system is so unexpectedly great. Tying together shields with a weapon 'heat' mechanic so it's not just constant weapon spamming and/or waiting for shields to regenerate was an incredible decision. It both simplifies the system from having shields and weapon energy, and also makes it more complex.
I kinda wish more space games with shields did this now.
Amazing work!
