This App is a 'seesaw' ride.
Your friend is waiting for you getting ride on the seesaw board.
You can move the character by tilting the iPhone/iPod touch with the Accelerometer.
[To Get Off] Touch the top-right rect. The characeter moves to the initial location.
[To Get On] Walk to near the center of the seesaw board. Tilt the screen back and forth to play the seesaw.
Touching another top-right rect, the image picker for the Photo Albums is opened. You can change the face to your favourite photo, such as yours or a friend's laughing-out-loud face, ... whatever.
