Press the flag. To move, you have to press the right arrow key to switch the slides, if want to go to the previous backdrop, then, press the left arrow key. If you want to stop the music then, press the down key, if you want the music then, press the up arrow.
It is a really cool magic trick, I liked it, so maybe you will like it as much as I did. (Warning) THIS CAN BE VERY ADDICTING!!
