it is great. I see the tilt(lean) of the rock tower kinda facilitates the whole thing?
And so, it is simply that, fall onto it, even the wooden rigid ring part, and as long as it spins up before you technically hit it, you get away safely. But if someone happens to pass ahead of you, and it's not quite prepared for you you could just go splat... hmm k.. i can live with that, Kudos!
