> Jump in
You go ahead and jump in.
You are still falling, and falling, and falling, and falling. You see an even darker patch of darkness below you. It could be the start of a new adventure, or it could be your end. You find an answer: you go through the patch which is apparently not solid. You land in midair below the patch.
> Look around
You can't move for some reason. You look forward. You see a bloodshot eye that looks demon-like. It roars, "Your adventure has begun! You shall travel across the planet to find Pandora's Box and the Holy Grail."
