The only idea I have left but it bugs me for a few days now. Let's assume the Ruins are actually a map:

I mean especially the areas marked in white. Could the indicate a movement in a certain direction? I remembered that on drawings and comics a motion is always indicated by special "doodles"
So the planet would go clockwise, while the rotation of the planet itself is counterclockwise - if you take the marked area as "tail". Coincidentally 1 B rotates counterclockwise, since it says "-6.9" days in the System Map. Am I wrong about this one? If not, I find it interesting.
Why is it not working to put that picture itself in...
I think we're on to something here. Or at least it has merit.
Let's use what we know.
1. The moon orbits directly above the Large and Small circular areas. Rising from the bottom of the map we all use and setting from the top.
I'm going to make some assertions that are guesses.
1. The bottom is the "start" point and represents where we are. Specifically the sun1. With a single ring and 5 planets.
2. Using the outer raised section as Planet 1 because it's the first to be crossed by the moon and going counter clockwise we have a single lined jut with another line from it. That is 1 B with its moon. Continuing counter clockwise we get the other planets for stellar body 1
3. The "end" circle where the moon sets is the destination. Maybe it's in this system. Maybe another. But it's a dual ring sun with 5 planets due to the breaks in the rise and counting the one outjutting line as a planet that's the destination.
4. Since the imaginary line of the moons orbit crosses the lower raised section that's planet 1 of whatever system/sun this is. Making our destination planet 2. Since this line doesn't have a sharp line shooting off from it this could mean it doesn't have a moon. Or the wider rhombus could mean something relating to the orbital plane of the body that is related to it.
We need to break these sections down into angles and see if that ties in with the orbits of the moon of the planet were on as confirming existing elements we know gives us greater confidence in our theoretical destination.
I also think Mengys idea about the raised section referring to the galactic plane is right on. Not sure if this would refer to Sol though as I can't imagine why aliens would. But a species from Earth who made the game may well have done that too.
