Can you make the heavy oil wells easier to see on the map? Maybe also have some right near your landing point, like Vulcanus does with sulfuric acid.
When I first landed, I thought I had to figure out how to make oil from sand. (Didn't help that I got confused by some Moshine products, but that part isn't your fault.) Then I realized there were heavy oil wells, but even when I was looking for them, the color was so close to the sand color, or the color of the crash remnant pods, that they were barely visible on the map. Once I know what to look for it's clearer, but they just look like slightly bigger blotches on the sand at first.
I know you're limited by the colour of the heavy oil in game, and you want that to be the main colour, but a pop of some colour that isn't reddish-brown would help a lot. Maybe a rainbow sheen on the edges, or make the steam rising off them more colourful somehow?
(Cool planet, though - it's the first custom one I've tried, and it does feel about as well-designed as the canonical planets, which is impressive for a mod. Thank you for your work on it.)
