Marsh/First moving platform

Name of the puzzle in game files:.

Manifestation of principles: The first moving platform confirms that in puzzles the areas containing polyominoes represent the platforms on which you walk, and the areas without polyominoes correspond to water. It does so by letting players notice the similarity between the puzzle's content and the surrounding platforms. The motion of the platform is also a realization of the concept of connecting distant/separated areas, which will be important in the next row of puzzles.

Tutorial for: It also teaches that for some puzzles this representation works in both directions: the state of the puzzle represents the state of the environment and the two are linked so that changing the puzzle's solution will trigger a synchronization of the environment's state and make the platform move.
