I just felt like having a minimap would make it easier to navigate, especially if the map only shows the parts that you have already explored (but I think that it was easy to navigate because of the reasons you mentioned). This way, you would know where you have been, making it clearer where to search for e.g. fuel. You can also easily see which parts you have not been to. At the same time, it would be preferable if the minimap only showed terrain and your current position. (I also like to have an overview of the world I explore). Though, I would like to add that I think a minimap is not necessary, but more of a suggestion. I do agree on the part that a minimap could damage the feeling of exploration, and it can easily be used in the incorrect way. Anyway, it was fun playing your game. I hope to see more!
