use the arrow keys to change the size of the meteor, be careful though.. press space to unleash your custom meteor onto the earth and watch as your planet gains rings, moons and even craters on those moons. if you want to mess around try holding down spacebar!
WARNING: I think certain orbits may be bugged and if you look inside you will see spoilers for future updates... oh and don't try zero size because it ruins the game(experience?) New Update: now it says 2016 :D
