I'm not particularly a fan of visual novels that do not have player input, so I might not be the intended audience.
For the things I like, there are quite a bit of illustrations and the composition for many of them is really good, in their current state they make me think of the early storyboard drawings that sometimes get included with the artbooks of games, if each of them were to be polished I can clearly imagine the opening of a visual novel highlighting many of them, my favorites where the Yagoo introduction, the Kronii with the flags and the ERB one with the rest of Justice.
I appreciated the few sound effects at the start, but I noticed there weren't other sounds for the rest of the game. I would also recommend having either music or ambient sound if possible, it is a bit awkward to be in silence during the entire thing, specially if you read slowly like myself.
The end is abrupt, but we were all limited by the deadline (how theme appropriate) so it is understandable.
All in all, well done completing your project!
PS: I think it would be fun to see something like an animatic with your illustrations.
