It's rare for me to get intrigued by an evn, especially a demo but honestly this ticks all the right boxes. Art is visually pleasing, dialogue seems to flow well and feels like it matches the character design and the music similarly also seems to be a match for the scenes. Multiple meta layer story seems like a nice hook, especially the weird interview. Only negative that I really noticed is that on v.4 you can easily click past the ""hanging around"" scene but it could have been due to playing 3.0 already.
Definitely looking forward to reading next versions.
