spoiler, striking through
My Ending A was a run where I could not find the elevator key and had convinced myself it would never be found, that this PC would die in his apartment for having failed to leave it despite knowing better. I was touched by this tragedy! I began to despair of my options and tapped on the couch object for at least twenty seconds, I wondered if you had put it there so as to get a rise out of me. Then I found the key in the cabinet, rode the elevator and wandered in the hall for ten seconds before the black out.
My Ending B run I hit the cabinet right away but missed the message which I guess gave me the key, and I didn't see the E icon in the corner of my screen because I was looking at my cursor instead. I searched the whole apartment quickly then eventually went out to the elevator. This time I made it out the front door and was crushed? Then I did another run where I went straight for the door and got the same ending. I liked it!
