By the actual metrics of length: Code and script, this VN has already surpassed the largest known VN in the world in pure code and active script/story. So you can shove it on the fucking "Just because you said this doesn't make it true!" Unless you want different measurements.
I disagree on this quite a bit actually. I feel like I've played quite a few games that are longer in playtime, and I mention playtime in the sense of there is just outright more story and writing going on in those games than what's in the current release of this game.
Plus I feel like code length is debatable because you can have a bigger code as a result of poor coding that made it more bulky and it's not like this game doesn't have features just seem to break every other update or gets disabled (calendar/info card system?) cause it wasn't done properly the first time. I feel like there's been a couple things in this game that has had to be fixed because it wasn't designed properly in the first place and didn't play well going into future updates.
Back on to largest VN thing, it's sure enough to get there based on how it's going so far I just don't think it's there yet and to claim otherwise is laughable.
