I think better sounds should be added, as, to me, the sounds in game, are very weird, i cant make sense of what they are, and they seem a bit buggy(dont know), It would be cool to have like a ''pew'' sound for the cannon, and like ''swoosh sounds'' for rockets, and engines, be a little less loud, and make a sort of thrust sound, louder as you begin to start moving/accelerating, but as you have less force needed for acceleration, it gets quieter.
