Your game looks pretty awesome and I think personally that your space theme is goddamn nice.
Sadly it crashed once in the tutorial but my roommate says that it's Unity's fault.
About the real game, it ran apparently too fast on my PC. At least when I compared it to my roommate's one. When it's fast then it's almost Dark Souls in space :). But on their's it's much more enjoyable and makes fun. All in all a nice game :)
