Hi ! Thanks for your comment !
I'd be interested in seeing what you'd think would be the propre length for the demo of a visual novel. I just want to say that I am not planning to make a very big game since I am working on it by myself without remuneration as a hobby (also it's my first game, so I want to stay reasonable).
(Also I'm very confused by the "clicked through slideshow" comment since it's very much the concept of a visual novel ? Perhaps you could explain...?)
