First of all when you talk about a set of very limited choices, you mean a kinetic novel, not a visual. You can have a gazillion in a VN.
Secondly, I really do hope you don't make the same mistake as with your previous game. Creating all those messy flashbacks jumping back and forth, with a convoluted story just to show you're the Zack Snyder of adult games was never a good idea. The imagined artistic concept and the execution didn't matched at all, if you do that here as well, I doubt you'll getting any further than previously.
