Water hazard

Well I finished 2 more areas today, and one was a complex and tricky one involving a water-wheel, a waterfall, and a spring platform. After those made it to the second gate control, but it was getting too late to solve the puzzle.

I must be getting near the end of the game though since when I saved I got a trophy for saving at every save point. So either the the game end just after this puzzle or I have to back track like a metrovainia game...
