TellTale games and visual novels usually have choices, which brings an element of interaction to it. I get your point, there are VN with no choice option, which are just a form of story in the end. If I have to just read some text by clicking, what makes VN different from E-books?
I am not trying to blame the OP, they have done a great job porting a novel into a VN type scenario. I am just questioning if could actually be considered as a 'game' or not
