Very cool game. I love the art and style before the game begins and after the timer has ended. In-Game graphics are also ok, but I don't like how mouse works. I felt it was weird. It was a bit hard to get the camera where you wanted to have it.
Maybe when the timer ends you should show suspects' entire body and name. It is very difficult to tell which one is which. E.g. I had in mind that the suspect I will choose has blue shorts and white shirt. And after the timer ends only upper body is visible... Maybe you should make the suspects more personal.
Over all very nice game! I enjoyed playing it a lot :)
