I love this game! If it is not the best space game to exist, then I don't know what is. You can experiment with stuff or create your own system. The only thing I wish exists is a better black hole calculation system like accretion disks and stuff. By the way, you cannot create a planetary system if the star orbits around a black hole as the planets keep on getting heated and destroyed for no reason at all. Apart from the suggestions and glitches, 10/10 would recommend buying this game.
