Really cool game! The pixel art looks pretty good and the voice acting and music are great.
I liked the idea of not having a cursor and discovering how everything is not real (really fits the theme). You could really build on this idea to make a larger scale game out of this. There could be some other things which you can do other than walking as it becomes a bit repetitive towards the end but I can understand that 1 week is a really short time for making a game.
Overall, good job! :D
