Lately, space has been devoting too much time to the Earth, somehow it began to interfere with it or something. Either a huge meteorite will send, then an asteroid, then the sun begins to play pranks and arranges magnetic storms on its surface, then the Moon, a faithful satellite, suddenly wanted to get too close. It's time to Save The Earth, the earthlings thought, and installed a special shield around the planet that would protect us from all the troubles from outer space. But apparently someone in the Universe did not like it and a huge planet approached the shield, many times larger than ours. She began to pull the Earth towards her, which became a big threat. You must keep the Earth within the shield, preventing it from popping out. Play ping pong with the planet in Save The Earth.
