Fun app. Great graphics. Unsolicited feedback: The zoom functions are glitchy and it's often too easy to add an accidental celestial body. Haven't quite cracked how to add a moon to orbit a planet which is orbiting a star without it's path just being gobbled up by the gravity of the star itself. It feels like if I could zoom out enough and give each body some space with a little room to capture that may work. But to my initial point, the zoom functions are making that nearly impossible.

I loved the free version enough to pay $5 for the whatever version this is. I tell you, unequivocally, without reservation, that it was easily one of the best spent $5 ever. I thoroughly enjoy this game and while I might occasionally delete it to make room for something new, I always always come back to it. I find it both relaxing and entertaining, and just challenging enough. And the music helps me to fall asleep when needed.

So far, pretty fun and interesting. Not really a finished product yet in the sense there's no obvious objective or direction. So far I've only clicked to create different objects that crash into each other until they unlock a denser object, repeat until you reach black hole, then...? I've had it on full fast forward almost the whole time. If there were objectives such that I'd be guided to create systems or something, that would be cool. Example of solar system makes Earth life die before 6 mo.
