I just started and I'm told to go out the door but I can't see it because I'm out of the screen. I've attached an image below, I hope this would help.....
Seems like a resolution issue, which would be my bad. I should have designed it better for browser. Not sure how else to help but maybe reload the page and try playing without touching the zoom, keep it at 100%. The door is also right underneath where the broom is, and Nutmeg (The cat on the bed) keeps it locked until you talk to her. Hope this helps!
