Uhh... most of the game is outside the apartment, and exploring it is only a small part of the intended experience. You have to take the keys from the nightstand in the bedroom and then unlock the front door to leave. You weren't supposed to get lost in the house, I had no idea the language was *that* confusing.
Now I just realized that you might be talking about the "white rooms", i.e. the intro to the game. Actually, I agree that that one might be confusing, since you only see the key when moving counterclockwise and only see the door when moving clockwise. I think I'll change that.
Either way, please please replay the game. Move right, forward, take the key, move back, left, left, and push the wall.
Edit: I just changed it so you will always find the key and the locked door. Just restart once you begin.
