One grid square on the map seems to be about 100ls horizontally, but something like 130ls vertically. If you are going for a perpective effect, shouldn't the grid be perspectived, too?

I was so distracted by all this that I ploughed straight through the base while trying to measure distances instead of paying attention to hostiles...

Hmm. Also looks like something isn't working with the base placement algorithm, or you need to double check what is and isn't marked as a planet...
