Hi!
Thanks a lot for playing and feedback!
The thing with "why would I go outside now?" is unwanted behaviour with the door (and some other objects). Basically if you click the door 10 times all the "why would I go outside now?" will pile up in a queue and you will listen to them untill you hear all 10 :D. Will fix that in a future updates, but for now if that happens you can skip dialogue with "Space" button.
Regarding the key for the drawer - did you use the foghorn to advance in the story?
