Even with the step-by-step instructions, it was a bit unclear how to achieve the goals. As others have said, having instructions inside the game, and presented incrementally would be a great help. With a bit of trial and error I did get a rocket to the moon at least!

Thanks for playing! Yes, built-in tutorial would be really helpful. I also should have explained more clearly what each technology does, and included more details in the maneuver dialog, like the thrust of each component, the consequences of using it, clearer formulas for the calculations, and state of multi-turn maneuvers. I have plan to add them but finally ran out of time to implement...
