Very good.
Extremely good artwork and animation, easy-to-use (yet stylish) interface and seemingly interesting plot. Very good job, this reminds me of the good old times' point-and-click andventure games I used to be very fnd of.
One negative element is the huge ammount of film-noir cliches that you have included... I would go for something more fresh (I enjoy the atmosphere, but it has been done way too many times, especially recently).
Overall, I think we are all expecting the next part!
