Very cute idea! And I liked the Law & Order parody. :-) Nice interrogation room too - the banding on the light, I think actually helped with the aesthetic - I'm not sure if that was intentional or not. Overall, great job!
However, I had a lot of trouble figuring out what the state of my "suspect" was. The countdown to sleepy time was clear, but I couldn't really figure out what the different facial expressions meant, and never managed to get a confession. A little more feedback would have been nice
