This is an extremely cohesive game concept from top to bottom. I love how well the visuals serve the storyline and vice versa. Voice acting was also excellent. Considering the tactile feel, I'd love to see even more usage of photos and other aspects of surveillance documents. Maybe for example, if the images of the scenes you watch looked like surveillance photo/video? Or the images you can choose to identify the informants would be little thumbnail-sized images like you'd find in a file photo. Very evocative visual concept as it is though, and thank you for making it! It was very powerful storytelling, and a really novel way to use the adventure game medium.
I actually recorded my playthrough. If you want to see my impressions as I played, you can see it below (timestamp for your game in the description). Hope that can be useful!
