Which still look quite bad. Especially when you completely flood your planet, you have a spiky planet that is completely blue (the water is only a change to the texture)... Not sure how I would fix that. I've toyed with the idea of making the whole planet and asteroids 3D, but that seems like too much effort

I'm still not sure about the rainbowy path prediction, I don't think it's really stylish, but helpful for knowing if you are actually going to hit your target
