This is one of my favourite submissions from this year! I really enjoy the gameplay of trying to come up with a burn that gives an appropriate trajectory while still leaving enough fuel for adjustments. The messages were fun, and I appreciated the reference to Dorian's Door Emporium.
I feel like the game could do with more introduction to or feedback on gravitational influence/fuel usage. I think the large circles around planets are intended to indicate a planet's gravitational influence, but player need to deal with that before they reach a planet, and the starting area doesn't have that kind of indicator.
I feel like the core game would be stronger if players could infinitely refuel at a planet. This would allow for multiple launch attempts, and for stopping by an already-visited planet en route to elsewhere.
Great to see sources as always.
