It seems that you have after ~18 stars enough of it. I would guess that the controls were too clunky or the gameplay itself too boring for you, wasn't it?
I would understand that, because the fascination comes from the view and not really the gameplay. Until now at least.
Another black hole just showed up suddenly and absorbed my black hole. My first time play got about 5 suns. And after I figured out how to play, I got this high score. I think that you can make some visual effect on another black hole so that I can avoid it earlier.
