A very simple concept and quite satisfying. It definitely fits the theme 100%. It’s a bit of a shame that it isn't a puzzle-type game where you search for constellations and rotate them to actually fit something—that might have been an interesting direction as well. The visuals are cool and there seems to be a lot of them, which is nice. The gameplay itself requires virtually no explanation, so big props for that.
It's hard for me to say how this could be expanded further, though :(
