Interresting story, amazing cinematics.
Only downside is the manga style of the faces stands out like a sore thumb because the rest is reality smooth. I mean compared to another VN the faces look good, but compared to the backgrounds, the moving car, bodies and so on present in that very game, they don't look so good anymore.
Other potential downside, this looks like a ton of work, i don't expect the story to progress fast.
