-Use your mouse/finger to draw, and a line will appear between your dot and the dot in the corner! -Please don't complain about any glitches or bugs because I'm quite unfamiliar with the Pen function.
-The color slider changes the color of the line! -The size slider changes the size of the line. -In order to erase your current lines, you have to click the green flag again. -I made this randomly when testing out the pen feature. -Enjoy!
