In a game where at the very least one playthrough will involve save scumming to get the best outcomes in conversations, the skip button must not be the same button as the button to accept the first dialogue option. Especially when pressing spacebar one time too often is punished with such loading times. There needs to be an option to skip a line that does not risk picking an option inadvertently.

Make "skip dialogue line" and "accept dialogue option" two different buttons.
