Now, when you click the green flag, the birthday song plays, and when the song is done, it asks to click the cake. When you click the cake, the candle lights will be gone. In addition to that, I wanted to switch the backdrops, Party-1 and Party-2 back and forth to make animated confetti while the music plays. Then, when candle lights are gone, I'd like to have the confetti disappear. How can I do that?
