First of all let me just say that this is a beautiful, smart and atmospheric game.
The most interesting bit, however, was the description of early characters that I found in one of your blog entries. As a very clever man once said, design is nothing without the process. That's why it is always thrilling to follow an evolution of a concept.
We should probably make a "before/after" thread somewhere here to see how certain concepts are developing over time in people's projects.
Anyway, good work. Cheers!
