Explaining this design choice, the director says, “I’m simply not very fond of dialogue scenes where characters go on and on about trivial matters. I prefer the pacing and atmosphere of films. Of course, I believe games that emphasize dialogue have their own merit, like allowing readers to project onto the protagonist and soak in the atmosphere, so this isn’t about which approach is better or worse. However, I believe that the maximum amount of time a person can concentrate on reading text is about 4 to 6 hours at most, and I’m concerned that if it goes on any longer, more people will start skimming or rapidly clicking though the text.”
