Thank you so much for your great feedback. As for your concerns:
the ui not updating for the key was actually an oversight on my part, I really appreciate you pointing that out.
Unfortunately the no indication what to do after picking up key was a ran out of time thing, what you do there is you pick up any of the keys and bring it to the door beside the wardrobe and it pops open. Will fix that in future update. It was supposed to be that you have to figure out which key is the correct one and that will also be fixed in future update.
The lack of indication that you are about to pass out was also another ran out of time issue.
I will resolve these in the next update. Thank you again for the feedback.🙂
