That's the sprite from the Metal Slug games!

If you add some sounds, that would help too, I rather entertained myself while playing by imagining the black hole making slurping sounds anytime it sucked in the bigger things. You could stage the game like another commenter mentioned, perhaps duke it out with another black hole? Anytime the black hole gets a bit big for the screen you could scale up the stuff being sucked in. Since you threw in some aliens, why not have them be able to zap the black hole to shrink it (advanced technology and all). And as chezits said, more stuff to suck up!
