Super intense game! I really like this type of fast-paced mouse controlled game. Art and music is great! Two tips: the planets sometimes spawned almost on top of the black voids - you could avoid that with a hit-test when spawning. And the munching sound seemed to interrupt itself(?) when you eat planets very fast. Try using multiple audio sources and alternating between them to solve this.
i made the black holes a little small than the plantes, so you can eat then without obrigatory touching the black holes, but i think i didn't made this clear enough, about the sounds, very good hint, in later games o will do this way, thx for playing and for the feedback :D
