Cosmic Crystals 7-20

Cosmic Crystals 7-20 is the twentieth level in Cosmic Crystals.The objective of level 7-20 is to use the birds to eliminate all the pigs. Get at least 129,000 points for 3 stars.

Difficulty
This level is very hard because:
 * There are a lot of obstacles so it's hard to controll your bird.
 * Getting three stars is very hard.

Strategy
Send the Lazer Bird down the chute of the western planet. The resulting domino effect can destroy the tower next to the chute, but this is actually not ideal. Instead, if that tower remains intact, send the next Lazer bird south of everything. Redirect it through the wooden walls of the far-eastern structure. As the Lazer Bird becomes subject to gravity again, it can loop around onto the detonator on the crystallized southern planet, sending TNT into the aforementioned tower. Note: The second shot is extremely challenging.
