Can you untangle the mess of colored wires in this seemingly simple yet highly challenging puzzle game?

Click and drag the nodes at the end of the wires to move around and stretch and shorten each wire. Nodes may only pass through same colored wires, except black nodes that cannot pass through any colored wire, including black. White nodes however may pass through any colored wire and white wires can be crossed by any colored node. Every time you untangle a wire it is eliminated from the puzzle. Untangle all the wires to complete the level.
