Played it a little bit (going to play more later).

I think you need to rework the tutorial.  Basic flight tutorial doesn't tell you how to use starlanes and stargates and how to dock on stations (it's somewhere in the advanced tutorial, which some may skip for later as they might assume it's supposed to be read later, after they get hang onto basics).
Or maybe I'm too impatient to read all the text and that's why I ended up going through starlane on highengine or bashing against station trying to go through entrance (which is not marked much at all), but maybe some button prompt and/or pop-up text would be useful, so the player could learn the basics on fly instead of pausing the game every moment.

 I understand it's probably just a test, but voice-acting is irritating as hell and sounds like it tries to me comedy-ish. Normal text would be better already.

You can instantly start going back despite having forward thrust AND THEN start going forward at same speed you had before instantly.
