Had some fun with this. Figured out how to create a mission where another ships tries to attack me. It was a bit awkward to control rotation with WASD, I would hope that the mouse could be used for pitch and yaw, with QE remaining for roll. Or mouse being pitch and roll, and AD being yaw.
I haven't played other spaceship games before (except Air Brawl), so I don't know how it usually is. Hoping to see this updated at some point, I think having functional missions would make the game pretty fun already.
