Imagine being like Spiderman and able to shoot sticky strands of
web out from your hands. Using those elastic strands you just might
be able to attach to surfaces and propel yourself forward.
Simply click the mouse to shoot a wire straight towards the mouse
pointer. If close enough to a colored surface, it will adhere to it
temporarily and yank you toward it from the elasticity of the
string. You can have two wires in use simultaneously, hence the
name of the game. Use them to keep moving forward because the game
window doesn't stop scrolling. If you go too far outside the game
window (in any direction) the game ends
