I love the interpretation of the theme as planetary orbits!
I think one thing that could make the controls more intuitive is if the red and green axes reoriented themselves to be perpendicular to the centripetal force when you enter a new orbit. I ran in into some issues where I had trouble controlling my planet if the velocity got too closely aligned with gravity.

I do not want to remove the difficulty of having to plan your jumps between planets but i understand the struggle. Maybe they could be two separate modes like Momentum mode (the planet auto corrects itself) and Precision mode(the planet does not auto correct itself)
Thanks for the review as I plan to expand on this game in the future.
