I liked the vibes and the aesthetics! I also liked the idea, but the controls and goals were a bit confusing. It felt like the gravity screwed up my movements a lot of the time, and I kinda didn't understand why am I going one direction and not another.
I also didn't quite figure how to create civilizations? It would be cool to have some guide or recipes, even if outside of the game, in the game description.
Nice submission overall!
