White nodes

 are a recurring interactive objects and main component in Fault Line. They diamond shaped, with white things sticking out and a smaller pink diamond like node in the middle of the main node. The Player's cursor in the game is a target, which is used to make a Fault Line. When a Node is clicked, and dragged with the mouse cursor over to another Node, the area the line is spread across will be folded, thus creating a Fault Line.

With the creation of a Fault Line, it makes possible to cross areas previously impassible. If the Purple Robot makes a Fault Line, but crushes himself in the process, it is instantly reverted. Fault Lines can also be reverted by clicking a Node. If the Purple Robot dies, all his Fault Lines done after he was previously spawned will be reverted.

Areas folded by a Fault Line have a pink line across them. Fault Lines are many times used to fold away hazards that would otherwise kill the Purple Robot. Other Nodes already folded into each other can also be used with other nodes.

Trivia

 * Some levels seem to already have been folded when started, as pink lines are present in some places. These alterations cannot be undone.
