hihi! I came from the youtube channel and i'm loving this game (no really, i've been unable to stop playing for the past few hours aaahh) but i'm currently at the scene where riley declines austin's request for the cat. i'm not sure what you're supposed to do because the stairs to the third floor don't open. i think it's the door labeled 'F' but it doesn't seem to do anything. i also tried the roof and i'm not entirely sure if i'm playing it right-
if anyone has finished the same route could they offer some guidance?
