I figured it out too. Took me a while!

I was not able to figure it out without using your hint. After that room I was able to finish the area within 10 mins. For me, that was the one puzzle that came up short, as I do not think I would find the solution on my own. The rest of the game is great! Now I'm just stuck on the 5,10 star. I know where to go, I just don't know how to get there...
