Very interesting little webpage.
I always loved those choose your own adventure books. Are there any authors still making and releasing them? I haven't seen a new one in my library for ages.
(SPOILER)When you finally stop falling your not in the mansion anymore. You land in a barren plain. The sky is red with a bright yellow sun set in it. Not a single cloud can be seen. The only thing that can be seen is a single black tree naked of leaves. The heat has left it dry and twisted. You begin to walk towards it when the ground beneath you starts to shake. Small at first, the ground begins to crack open into crevices which grow as they streak towards you. You lose your balance as the shaking becomes more violent. Then giant evil tenticles burst forth out of the cracks! They whip towards you and OH GOD!
Did those tentacles do what I think they did... or am I just a naughty boy?
