This is really awesome! Great work! I do have a suggestion, not sure how hard the feature would be to implement. An undo button, with the ability to undo a few times.
Thanks for the suggestion. Do you mean undo some color changes? Or undo the seed generation? Never really did a feature like that so no idea how hard that would be.
I meant color changes, but seed generation would be neat too. Or maybe a button to revert to the original color palette, if that would be easier to implement than color undo. I was playing with the color a bit on some planets last night and thought it would be a useful feature to suggest.
