Thank you for your in-depth review. It's really interesting to see how people play my games. I definetly enjoyed your commentary!
You're right there isn't any audio, although there really could be some, atleast background music.
There's actually a scene where you have to choose between the different suspects, but you missed it, because you showed the right evidence to the right person before that.
You could have entered the 'desicion dialog' at anytime if you say that you're ready while talking normally to the butler.
Maybe I should look for another solution to this problem as I think it's natural to show everything to everybody before they think they can solve the case.
But again, thank you for your efford! :)
