Untangle by Tzomby is a puzzle game where you must resolve a series of nodes so that none of the connections cross over each other.

Gameplay

In this game, the player must attempt to drag the closest node to untangle the lines. Red lines indicate tangled lines, while green lines indicate resolved/untangled lines. The goal is to have all of the lines green, or in other words, all of them being untangled.
