The game is still being developed, and I believe there still only the first day has been released. Unfortunately it's a long road, so you'll likely have to be patient for a while to come.
Oh really? Well I guess that must have probably been playthroughs with a lot of talking, or extensively exploring all possible paths, or something along those lines. Either that, or it's a pre-release given only to some YouTubers/streamers for marketing purposes, but I'm not aware of something like that. Either way, I'm pretty sure there still hasn't been a public release beyond day 1 of the story.
