That was a cute game :D It's good that you can choose and name your planet, the mini planets in the shop are unique and have great designs (and great names OwO). From a pure gameplay perspective, I think it lacks some kind of danger. The closest thing that ressembles some sort of danger was fear, but I honestly didn't understand what it does, and how to reduce it. It would have been nice if the planets you bought did a bit more than orbiting around the planet, like the sun did for example.
Overall it was really cute and charming :D But when I meant to end the game, I didn't mean in way as.. explosive as this one :'( Congrats on your first jam !
