Very interesting game! I really like the concept, and I think the case/mystery was well-crafted. The only thing I would say needs improvement is just some general accessibility features for playing back and viewing the evidence. I think a way to skim the video evidence, or just pause, or maybe skim per section of subtitles would be better since it was a bit difficult to read some of the sections that went by too fast. The fonts overlaying some of the video footage are a little unreadable, you could add an outline or two to help with that.
Some of the text evidence was a little unintuitive to read, I had to organize my evidence so that some articles weren't fully obscured. Also, it took me a bit or two to figure out how to actually open up the case file. Maybe you could have a small bit of text/instructions to show at the start, or maybe allow it to be dragged with the mouse.
The final thing is it was pretty confusing to select which evidence was for the murder weapon, because the police report and autopsy report both tied into the murder weapon, (one of them also literally said "Murder weapon: "), so I think that part of the evidence was both shallow or confusing depending on the correct evidence.
I did like the assets and the art style of the game. It was fun trying to figure out who the killer was, and It had a very simple and close-knit concept that worked really well in this jam's theme and limitation. All in all, great job!
