    You should clear away what was drawn in a previous frame before you draw your next frame. It's like painting on a clean canvas verses painting on a painting - if you don't cover up what was previously drawn, it doesn't automatically go away.

    Add this line of code to the top of your draw() function:


    This will ensure you start drawing each frame with a clean canvas.
