I saw your game before and I tried to play, but there is no tutorial and I don't know what to do there. I can turn the engine off and the ship stops, that's cool. But the rest of the options and menus are overwhelming for me, and most of it it's hard to read (too small and too dark).
I can see that a lot of thought went into this, but it's not a very accessible game, or to my taste, so I better not rate it. If I can be a bit of a meanie, I would nitpick that the ship should keep moving after the engine stops, but I'm not the target audience so I can't say anything of value, except... neat graphics and nice music :)
