You can draw on scratch BUT there is a problem after you move about a lot then the clones stop cloning so the red square moves still but the black squares (drawing) stop being behind you. Sorry I don't know how to fix it check below I Fixed it by making have check points that deletes the clones.
Did the coding Also vote If I should make it delete one clone at a time? You all most do a 360 around the area before it deletes
