I dislike it quite a bit. I want the MC to be a fully fleshed character. Even being able to choose their names sits wrong with me, but that's easy to ignore, unlike the faceless thing.
No, I'd rather go at my own pace. It's not even just about slow or fast, but to be able to advance exactly when I want, sometimes rereading a sentence, other times skimming. I've tried Auto a couple of times and it felt weird.
Usually, I like it. Many times I find myself checking if there's a recommended route order and such, so that's one less thing to worry about.
Then again I tend to do all routes, so I can see how it can be frustrating if you are playing just for one.
