Press the green flag. When your result comes up, you can choose whether to click the 'How' button or not, although I'd say that the information recived from clicking it is interesting.
I was making a game that contained a 'Random character select' tool which randomly selects a character. However, in the process I had an idea - What if I was to use this for educational and helpful projects? So then I deleted everything until the Project had nothing in it then made this instead of the game.
