You will need 2 computers or devices for this. One will be on the 1 setting and the other on the 2 setting. Setting 1 senses movement, and sends the other computer a signal to play an animation. Setting 2 is for playing animations. They won't work without each other! You can change the sensitivity of the camera with Z and X. Also, only 2 people can play this game at once, or it gets glitchy. Happy Valentines Day!
