Difficulty
Getting three stars is very hard.

Strategy 1
Send the Black Bird along the southern edge of the gravitational field of the nearest planet. The bird should end up next to the pile of stones on the main planet, and the explosion often cause the crystal to rupture. If the crystal planet is not explode, restart level until you can do it.

Strategy 2
Send Black Bird to the nearest purple crystals and make him to slide to the iron bar that attached with the rope, explode it to make the two boulders enter the atmosphere. Send the Lazer Bird below the second planet, redirect him to the another purple crystals. Send another Lazer Bird above anything, redirect him to cut the rope that attached with the northernmost planet. Finally, use the Black Bird to demolish the remaining tower to destroy the crystal planet. This strategy makes more point than the first one.
