Nice put together concept. Interesting twist on the management game, I like the automation aspect of it.
It'd be nice to have some earlier weight stages to see progress a bit more earlier on. The controls are a bit floaty as well. It'd be great to have the space stations post-fixed with their size or something for selecting in the list. Maybe a way to upgrade the engines for travel speed or fuel/dump rate of existing ships after purchase as a future add-on?
