Alright, Thank you
Can you grow wildlife or civilizations there ?
I think no, bcs it's more focused about the planet and gravity things.
But that'll be great if someone can make that kind of game😁
That's a great idea! But this simulation is only about celestial objects, their mass, orbit etc.
It would be interesting to see such a simulation though. Imagine octopus jumping to the top of food chain getting smarter with all those extra brains.
