This was a pretty solid puzzle game. The last puzzle took me way too long to figure out, though. As for the story, I liked how the interface changed as the character's awareness did. You did a good job at making me feel for them too. I didn't get to open the first two doors in the dream world though (probably because I didn't sleep enough - I thought bad things would happen if I did, lol). Also, nice adaptive music.
Great work!
