Well first off, YOUR TEXTURING IS AWESOME.
Now that I have that out of the way... YOUR TEXTURING IS AWESOME. The museum area especially is just crazy-detailed. And the music there is really neat, too. Did you compose the music?
Okay okay... so anyway, I like your idea of not actually being the one dreaming. I also like how your "avatar" doesn't have a name or anything, but I get the feeling we'll learn more about her as the game progresses, as well as Murula.
The other thing I enjoyed was the way you enter the dreams, by falling through that abyss sort of place, with the (once again) beautifully-textured background.
Now I need to ask tough questions - what is the overall tone of this game intended to be? Because I get a lot of mixed feelings - some sadness, some serene beauty, some creepiness, and some quirky, funny pars as well (ohai... bunny?). Perhaps a clearer tone wouldn't hurt.
I found one effect, or mimicry, which was the light, and I liked it, but it didn't actually ward off the darkness in the museum. Although I'm assuming you just haven't made that part yet. I couldn't find the second mimicry yet.
I liked that you made me take off my coat. I did it on my own at first, then I went back for it, but she stopped me. hahaha.
And once again, that museum is boss. I can't believe how much detail you put in it.
So... yes. You've got a good foundation. I maintain that it would do well with a clearer tone. But otherwise, neato. Keep at it.
