Cosmic Crystals 7-30 (Angry Birds Space)

Cosmic Crystals 7-30 is the 30th level in Cosmic Crystals and the last level to date.

Difficulty
It's extremely hard to feed the asteroids to boss. And this level is almost impossible to get three stars.

Strategy
Lightly nudge the asteroid in the southwest of the level, having it settle in the wormhole nearby. The rotating boss spaceship will eventually pull it in on itself. Try to do the same with the Blue birds and the next asteroid. Use the Lazer bird to detonate the TNT on the northern planet, sending more asteroids in the path of the boss’ ship. If you have hit the boss twice, send the Black bird straight ahead for the kill shot!
