New Playground

So, there is a new trail in our neighborhood that leads to an ergonomic-looking playground. I don't know if you can call it ergonomic since it seems very unsafe. It's not completely done yet (or at least I'm assuming since the swingset is missing swings), and I'm not quite sure how anyone under 34 y.o. plays on it (I picked that age because even Daddy had trouble). How does this equipment function and do you need to sign a liability waiver to use it?
