Piston room is just a path. You go straight and there you hit what appears to be a dead end, except there's platforms going across the gap, with nowhere else to go one will assume this is the way. It's a path. You'll follow that and your path will end up going left. You follow that to the next dead end, you turn around and yet again there's only one direction to go *unless someone is just going to retrace their steps* And idk, I still think just flaunting your jumping skills in their face is more harm than good. Like I said, they know the jump they just can't make it. It's not a simple case of "monkey see, monkey do" there's no eureka moment of "Oh! I'm suppose to press X to get over that gap!" *which is the kind of thing I had been referring to when I was saying that pointing out the ledge would be an asshole thing, because it's obvious and they are trying it already*
