Oh no problem. I'm guessing I was stepping on the "final plate" that overlooks the path of piping that the water pours down. You could have the other plates open ended on order (to push on exploration and not feel the need to go in a specific direction) and do something to lock that last plate until the others are pushed (like a barrier or some lights on a pole that light up when the others are pressed down on). Just some thoughts. Really nice idea. Good luck and I hope the team feels proud of what you all did!
