The music and overall atmosphere is fantastic. These sort of time sensitive, Victorian story lines often expect the time period that the story is set in to provide that inherently. So you've done a great job on that for sure.
Graphically, it feels a little sluggish. A lot of repeat aesthetics right out of the gate isn't really a good sign in that regard. I would suggest spending some time on the creation of new sprites to dot the hallways. Just to keep the environment ever changing in that regard.
Controls are simple and effective for a point and click adventure. Although, I find the most gratifying experiences offer a full "action" tool bar. Walk to, look at, hit, combine, and so forth. It might be something you could look at to expand the player experience.
Finally, the story. It's hard to really pass judgement on it this early in production, but you need to keep in mind that this is a story that we've all seen countless times. I sincerely hope that it deviates from what we've come to expect.

I'm expecting a good game out of you!
