Add more sides with the slider on the top left of the screen. Click on + to add by 1 or - to remove by 1. If you move your mouse pointer to the bottom left of the screen (or probably hold your finger there if you are on mobile), (probably) some nerd stats will show up. Move your mouse away from it to hide it. Try pressing SPACE or B. They both do nearly the same thing. See what happens.
This Polygon Creator is pretty simple, I think. The only credit that I'll give to is the Pen extension, Mathematics and Scratch. It will decrease the distance if it detects that it is touching the edge until it is not touching the edge at all (just barely).
