TL/DR: I want more.
It's actually got me interested in seeing it all the way through. I think there is a lot of opportunity to expand on the immersion: add more flavor to the journey.
So I had some ideas: Instead of a finite amount of time to complete gathering all of the evidence, how about you have to gather as much as evidence as you can in the time frame. You meet with the handler every 7 to 14 days, and hand in the evidence you collected. In this interval you can incorporate something like a "upgrade" shop, which can help you when you are making a decisions and dealing with cards. Maybe incorporate multiple decision trees. Everytime you meet the handler, it could trigger a card draw where you take a permanent hit to one of the 3 stats - making it harder to recover or increase through decisions. When any of the stat get's to 0, effectively all the evidence you've gathered is added together and gives you a chance to get Tony arrested, + a final score. The replayability would come with trying to get through the scenerios faster, or efficiently. Just musing around with some of the ideas here.
Over all I really like the direction and the premise, just want more immersion. Also, absolutely keep the animal cutouts on top of human bodies, it adds to the visual immersion of the game. Maybe that's how the protagonist actually views all the people around them.
