This was a really cool game! The cases were well written and engaging, I appreciated how the dialogue and evidence screen present slightly different information sometimes, so you really have to review everything and think critically about it. Apparently, I'm a pretty bad detective lol. The music and vibe was nice even with just one track.
I think some stronger visual elements would help this style of game. maybe some animated character portraits, or "case photos" of the crime scenes to help with set dressing. I understand from a previous comment that it would be a large undertaking to make tons of images, which I absolutely understand. It just came to my head when playing.
When I started the jam, I was initially planning to do a noir detective game as well, so personally its especially really cool to see that idea realized in some form! Awesome work.
