I can't answer the question about where it's going since I think you already told me! But I don't have a really clear sense of the protagonist. I know her name is Adelaide and that she's from London, and she seems to have a similar kind of "pragmatic" approach to finding herself in super-strange surroundings as Alice does in the original work. I don't get as strong a sense of personality as with Alice in the original work, however, since in the book Alice is always doing a particular sort of bantering or disagreeing / questioning in a smart, nosy, inquisitive kind of way. Not how "most people" would react in a surreal situation, I think? So it feels like there's still room for more of Adelaide's personality to express itself. Maybe with choices of some sort. There are a few moments (like when Adelaide says "Curious.") that it feels like hints of Alice emerge, even before the Dodo scene... but it'd be stronger if it was in contrast to Adelaide's own personality.
The mood is VERY American McGee Alice games -- twisted, dark version of Wonderland. This too is a little tricky -- like in those games, Alice remembers what Wonderland was like before (as does the player, presumably) so there's a strong feeling of "what HAPPENED to this place." Adelaide, however, doesn't have any previous connection to Wonderland, so it makes me wonder (no pun intended) whether she needs to react to the descriptions more in order to have their effect on a person come across more clearly?
