Hi! I'm one of the developers.
The constellation is the result of a little challenge that I and some of my friends did to find the closest constellation to the center. We also started to fill the center with as many constellations as possible!
I got lucky and managed to put the flag on the central constellation myself! I like the fact that I can explore the game even if I make it, thanks to its procedural nature! :)
I'm so happy that someone found it!! :D
