The Dink Network

While I was trying to complete all the tasks for entering the final maze, I entered this area near the base of the plateau where Dink just stepped into the water and onto the maze. I could also walk freely on the water from island to island in the maze. Was this supposed to happen? I only completed two of the tasks, but I managed to find the temple where the crystal is. After I got the crystal though, Dink entered this blank, dark screen which I presume is the ending. No Scourger. Nada. What's going on?
