Wow.
Wow. I love the dark theme and the way it's brought across. The sound is great, and you did a nice job with the background art and the characters. I love the rabbit, he's just cool, though the "before you die" thing was a bit corny... If I were you I would have said "I hear it's a marvelous place to visit so close to the land of eternal nothingness." Or something along those lines. Also, the part where she fainted was very nicely done.
Now for my criticism: The walking was odd, her feet slid across the floor in such a way that it obviously was a moving animation along ground, not a walking person. In addition, some of the background art didn't fade well into parts right next to it making it hard to tell what's connected, though that is hard to fix. Also, the backgrounds had a lack of a sense of distance, sometimes things seemed hard to tell the size of, with the only decent ruler being the cars in the walls.
