People have different paths in general. It is your duty to guide them to their destinations.
The object of the game is to guide the "pipol" to their respective destinations. Each and every one must be guided safely in order to complete 20 levels of game play.
A strategy to this game is to be careful not to dig holes too deep because it will kill the person falling in it. Try to do a "zigzag" dig so that the tunnel will be safe and flexible. Good Luck!
