Wait! One Chapter To Go!? I thought we have at least 2. One to sort out what happened in chapter 4 and one where we face the final boss.
While on the subject of chapters, is it possible to have a chapter 0 or a prologue in the future. I don't think chapter 1 does a good enough job to explain the world we're suddenly in. I'd even be happy with an introduction slideshow that said something like: "This world has vampires and monsters running about. Rinaldo was a legendary vampire hunter the killed the vampire queen. He's now deceased and vampire hunting organization is being led by his two daughters."
