It's a skill game where you'll have to dodge all enemies to get to Earth.
Enemies can appear on the sides or bottom of the screen.
As an exception, wind clouds will forcefully throw you to one side of the screen without causing you any damage and storm clouds will break the electronics the first time, swapping left and right controls, and will destroy you if you hit them a second time.
Be careful some enemies shoot!
Will you make it to Earth?
