Use the arrow keys / WASD to move the left dot. Press x or c to change the pen colour. Turn on Turbomode to load saved projects instatly. If you use save online instead of "Save" you will get a much shorter code, because the original code is saved in a cloud variable. To prevent the risk that your drawing will get deleted by mistake, still use the longer old codes! Except the costume for the mirror and the idea of a mirror, this is all made by myself and no single block of code from the original project is used here.
