I think that at the moment the game is a cake without a filling, and I think that you need to develop its appearance.
The game itself is very beautiful at the moment, but it lacks some features.
Here is what I mean:
I launch a rocket into orbit, but I have nothing to do with it.
From the game you want to get visual pleasure, so you want to add some interesting pieces to your rocket: scientific sensors, moving things and all that.
Thermometers, Barometers, Deployable Scanners etc:D
Of course, the game is in early alpha (or beta?), And this is not the primary task, but I think this is an important part.
