For this challenge, I will be posting some video support on Wednesday. In the meantime, you will need to start looking for clues in the areas where movement is noted. Particularly movement related to the X and Y value of the pointer or cursor. When the mouse or cursor moves the X and Y value for the cursor or mouse needs to be constantly updated and recorded. A drawing app takes advantage of this by leaving a coloured trail as the cursor or mouse moves along this X/Y coordinate path. Hopscotch and Scratch each use slightly different keywords to accomplish this, but both are found in the movement or motion block sections. That's the place to start looking. Good luck.
