To rescue the friends waiting at the starting point of this dangerous valley, draw a line with the mouse and after reaching the other house, click the left mouse button to let the passengers slide down the zip line. The longer you hold down the mouse, the more passengers will slide down the zip line. To avoid dangers, you can draw the line around blocks and move it like a rope. The game's mechanism is based on whipping a rope.
Use the mouse to play the game.
