Wow its an awesome tool, I really like it!
Can you add a stand-alone executable exe to the download? Right now only work in the browser on this page, or if you download the Godot engine and preview the tool. When I start with Godot and "Play", the PNG or spresheet download function is not working in this way.
Bug report: Gas Giant 1 has not been rotated when you change the slider (other planet types are work as intended).
Feature request:
1) Can we change the color palette of the planets? It will add more diversity, and create stunning, unique looklike planets like toxic, wasteland, desert, cloud only.
2) Turn off the clouds feature? Checkbox feature if the clouds not needed.
Cheers and thanks for your hard work.
