I got to the area where you put the vase on top of the nightstand but I couldn't figure out how to get past the area after you get the key. it is just a black knob on a wall that cannot be interacted with. plz help. i like this game.

I am a Turkish player and I will try and play this game as soon as possible. I got the key of the game from the forum you gave. I wish you continued success...
