Theres no "Game" Its just series of scenes. In visual novels you should at least add a few choices that change the story based on what you pick. (even if it means you not adding new scenes, but instead have it be a scenario where if you dont pick the right choice you dont continue w story. That way it feels a bit like a game and keeps me invested. Or else I just hit skip and watch the story rocket all the way through uninterested.)
