I get your idea, but since it's my very first game, I don't want to make something too complex and that's why I decided to start with a simple VN.
I know my game has low interactivity, but taking into account my little experience as a dev and the amount of my free time I can spend working on it, I prefer to complete a simple game than to fail making a more complex one.
So I don't plan this game to become something more complex than a linear VN, with choice based interactions and events. It won't become a "sandbox-like" kind of game as it's something I'd prefer to do for my next game, once I'm a more experienced dev.
