Use arrow keys to move. Remember, don't touch purple! Inspired by @Hiddentwig
For @Hiddentwig: To stop it from touching the purple, try this: Use the starting block. Connect it to a "Forever" block found in the Control. Inside the "Forever" block, put a "If-Then" block. Inside the "If" part, put "When Touching Colour..." and set the colour to purple. Finally, put a "Go To" block with coordinates set to START.
