The physics/math right now are kind of limited... it only applys gravity towards the "closest" planet, one at a time but it judges that based only on the center of the planet and not at all on how big it is or how close the surface is. I was thinking about trying to improve that and add some nuanced effects like you're suggesting. I also was considering adding a black hole or singularity entity as something that could apply gravity but NOT be something you can land on. Lots of possibilities for sure, I'm always open to suggestions for post jam improvements if you've got them. Thanks for the input!
