Connecting distant or separated elements

There are multiple realizations of the principle. For instance, connection between distant elements can be done with the following strategies:
 * Navigation, i.e. transporting yourself from one element to the other;
 * Moving one of the elements closer to the other;
 * Revealing hidden paths between the two distant elements;
 * Performing intermediary steps, reducing each time the distance;
 * Selector: having an element that allows you to connect multiple elements, but which can only be used to connect a smaller subset of these elements at a time.
 * Creating another kind of link between the two elements.

Connecting close but separated elements always involve to cancel the separation and can be done in different ways depending on the type of separation (the most obvious example is opening doors, but there are other less obvious examples).

Marsh
Because so many things are separated in the marsh, progression often requires to connect distant or separated elements. This principle is so important in the marsh that it is associated with the color Red when it correspond to the effect of solving a puzzle or to the strategy to use to solve a puzzle. See the Marsh page to see how it is used as a game mechanic to progress in some puzzles, notably in Rows 3 and 9.


 * Navigation strategy is used with the moving platforms.
 * Moving one of the elements closer to the other is the strategy used in some environment puzzles (first and second moving platforms) and in perspective tricks (statues joining hands and branches of the trees creating a dove outline).
 * Revealing hidden paths is the strategy used with the tunnel under the red pool and with the shortcut from the upstairs structure to the dock.
 * Performing intermediary steps is a strategy used in the design of the whole Marsh area (with all its separated but ordered rows of puzzles) and for going through the red structure.
 * Selector is a strategy that can be used with the second moving platform, although this platform can also be used as a navigation system.
 * Creating a link between the two elements is the strategy used in the puzzles of Row 3 (the link is the polyominoes) and in the puzzles of Row 9 (the link is the area with fully cancelled polyominoes).
 * Finally, the cancellation of separation is the only difficulty for the underwater room environmental puzzles that involves the colored pipes and the circular glasses, where we need to cancel the color difference between the pipe and what is seen through the circular glass.
