I'm not an expert reviewing cases (heck, I'm a newbie to the forum and already want more fancases), I will talk about whate I've liked, and where I could improve it:
I've loved the case. Everything makes sense, the story is enjoyable and I've been interested until the end, mainly because it fit post Dual destinies really good (Justice recovering) . In fact, one of the strongest points is Vladimir. As a character, he really wants to seek the truth. Reminded me to Edgey a little bit, which is always good. The theory discussion fit the theme too, and as a game mechanic, makes the case stronger. Mainly because encourages to really think what happened, and is great to introduce new theories, for example the failed abduction. Liked that a lot. As a prosecutor, was very well done with the duality he represented, I think its a very notable innovation.
A think I missed was a bit of character development in the first trial: Maybe the bouncer and the true culprit could improve, the first one, seems like a good character material for more cross-examinations or to help the delopment of the other characters the true culprit or the old man. Don't know. In the case of the culprit, it was very fast. One second testifying with a good breakdown (pyrotechnics) and then it's gone. I don't think the pace was the problem, but maybe a little bit of background to emphatise better could be good.
I've got a question there, why she was so sure about the evilness of Yuri? I mean, it seemed to like she was convinced he was truly super evil (he was, ofc), like Andrew and had to frame him no matter. Maybe it's just me that I got that wrong.
As for the rest of characters, I liked ashley, the detail of wearing the jacket on in court is a nice touch. I Loved Andrine, one of the best new characters in the cast, with exception of Vladimir, reminded me a lot of myself because we have the same sense of humour and the goodman sprite was very cool to see. Regarding Yuri, I would have loved more background too because the character had potential, specially with the evil eyed looks.That caught me totally by surprise, didn't think I was getting a evil defendant this time.
As for the art, I was surprised of having a lot of new characters, and the sprites were well finished with a lot of work behind and the breakdowns were well done (When it comes to games, I'm more of the programmer and the storywriter than the artist, so for me they work super good). Music nice too, well chosen and fitting.
Going back to the first trial in detail, I loved the plot because it just at the start it remind me to one episode of detective Conan I watched when I was a kid ( I think, maybe im totally wrong) that there was a body hanging out with a tablecloth or something similar, and when the window was opened, the body would fall, so everything ended in a nice coincidence in my mind, and got me engaged since the beginning.
Another Idea that was good, police reports. God thank you took the time to write them and make the maps as clear as possible. Took a break between the last trial, and when I came back, I wasn't asking myself what happened exactly (usually take notes while playing).
One little thing that might be a mistranslation:
During Vladimir Theory in the second trial noticed something that sounded weird to me. There's one statement ( the third or the fourth) that was "Once dawnstairs killed the defendant with the pistol", should't be "victim" instead? (I'm not native english either but sound weird)
As a TLDR, loved your case, It was nice of you bring us a translation, I imagine the original has more puns, and things that might be lost in translation, but hey, I would replay the case in the future if I'm need of a good case and I can't find one that haven't played. I spent today's afternoon and night, and was a well spent time, had a lot of fun, and It has helped me a lot in the future if I want to write my own case one day, so thank you
( and sorry if I made spelling mistakes)
