Start by pressing "S" instead of the green flag. The Up and Down arrow keys change the speed of your Controllable Earth. The Left and right arrow keys change the Earth number and each Earth has a different set of controls. To reset everything, press "R" if there is a problem. Earth Number controls: Earth 1: Follows your mouse. Earth 2: Moves towards the last location you clicked. Earth 3: WAYPOINTS!!! It is simmilar to Earth 2, except it memorizes everywhere you click.
The first two Earths were easy to create. I showed what I did to my dad, and he mentioned waypoints. It took me a long time to figure out how to do this and I had to use a few blocks I never learned about. Earth 3 was the most challenging part and has ... a significant amount more code blocks then the other two controllable Earths. I am aware there is a ... graphical bug when switching between off of Earth 3. This may not be the finished product, and it is really just to mess around with ideas. I really came up with it all.
