This game is designed for hands-free control.
The butterfly is flying over a pond. Navigate the butterfly, and avoid being eaten by the lizards.
In contrast to the usual games, this game is played hands-free. The device front camera recognizes the lip gestures, and moves the butterfly accordingly.
Smile widely and hold, in order to turn the butterfly clockwise. Round your lips and hold, in order to turn the butterfly counterclockwise. Adopt a normal lip position, in order to go straight ahead.
