A physics based twin-stick shooter about surviving as long as possible and getting a high score.

You're situated nearby a black hole, doing science-y stuff with gravity manipulating equipment. Then suddenly, alien scout ships appear and seem non too friendly about messing with "their" black hole! They attack! With no weapons, other then your gravity science equipment you defend yourself the only way you know how:

... throwing space rocks back at them!

Survive as long as possible as the game gets increasingly hostile over time.
