The demo was very short, so I don't have much to say ... but I can say that the story seems to be quite interesting and I really want to see what happens in it.
Also, I loved your art style (it's VERY good)
I'm really looking forward to a full version !!!
(and I'm sorry if my English is a little broken, I'm not very good at writing in English, since it's not my main language ´-`)
