I'm not even sure where I should start?
I love the characters, Lillian, Ray, and of course our femme fatale Inna.

The artwork is beautiful, a pleasant visual style that makes me want to see even more characters. (Inna at the party, in that dress? :) ) 

I would love to see this game from start to finish. (the -proper- finish it deserves).

For a demo? It wets the appetite, unfortunately to such a degree I really really want more, sooner, that is likely.

The characters make or break a story, especially with this limited a cast. I do hope, we someday get to see a happy ending, both for the assassin, the student, and her father.  I'm really really rooting for the lot of them
