Defend your beloved planet! Launch the robot scout to destroy incoming meteorites and protect your planet from destruction! How to play: * Place your finger on the center of the planet and drag outward. Aim at the meteorites and release the robot by letting go. * The launch angle and speed of the robot are determined by how far and at what angle you pull the line. * You have a grace period to launch the robot. After that time, the meteorites will start to plummet down. * Each time a meteorite strikes your planet, it loses HP. When the HP reach zero, it's game over. * Collect planet pieces and combine them to create your own unique planet -- then tweet the results to your friends!
