Great! thanks for playing and leaving this detailed feedback! yep, i get everything you are saying and the 6DOF is related to the EVA gameplay, outside the ship, that may have sounded a bit confusing...
The missiles inside the ship are merely to test the interior placement mechanic, its a demonstration of the system, no purpose as of yet, like most things in the game right now...
The asteroids are also just things to look at.
I will implement the speedometer fix and the movement feedback ASAP!
