HIT DA FLAG AND ❤! Click 'Allow' to the security pop-up (don't worry, you won't be recorded) or it won't work. You can draw on yourself once I get that feature working.
I kinda got the idea from @LoveMyFamily's iPad… Double click on the moustaches and hats to change their size. Double click on the colors to change the pen color. To get the pen working for now, click 'See inside,' then click the green flag, then below the backdrop by the list of sprites will be a box with a check in it. Click the box and then you will be able to doodle. NOTE: This is a work-in-progress!
