Nice, that looks really cool! I like that you can even click on the planets to see a map of the world. I can see that you put a lot of effort into it, thanks for sharing!
Thank you! The planets had a very limited tileset (there's no lava, no moon dust, etc, so moons lava worlds and deserts look the same) but I wanted to see if I was capable of procedural generation. And it would seem I was. I have plans for a future space exploration game using your programs (and a better, larger tileset). Is that okay for you?
