I really found you guys nailed the theme and incorporated into a innovative mechanic!
If I had to say something would be to have some sort of name tag or picture on the dialog box... took me a while to figure who was talking each time, since I was changing a lot. Also, at some point I just wanted to try my luck at a guess... hahaha! I wish I had something like 'tries' and got penalized if I guessed incorrectly, but the game still allowed me to try if I had 'sufficient' evidence..
Overall, great entry! Congrats for the team!
