Your drawing is saved in the cloud and will auto load when you start. To save, go to settings and click save. A low accuracy value increases the fidelity of the brush. Thanks to @DadOfMrLog for color picker code, the original project is at http://scratch.mit.edu/projects/10941245/ . Drawing accuracy has been decreased to allow for greater cloud capacity
