Captured and Sent to the Nineteenth Floor of Hell from the Start

This eerie world is full of mysteries. When night falls, don't go outside. You never know what strange thing you might encounter: a headless knight, a colossal monster with a human head and a snake's body, or perhaps one more step forward will send you plunging into the depths of hell.

What kind of monsters will I encounter if I stay until dawn? And where will I end up in the end?

I don't know either.
