Red Planet 5-22

Red Planet 5-22 is the 22nd level in Red Planet.

Difficulty

 * It's one of the considerably hard level so you have only 3 Lazer Birds to do this job.
 * It's even harder for some new players.

Strategy
Launch Lazer towards the top fiery asteroid and redirect him towards the stone blocks to the left. The resulting chain reaction, with the help of the steam geysers, should destroy all the pigs.
