Thanks! Just watched your playthrough, and I enjoyed your commentary and reactions! If you do ever revisit it, I recommend you check the window... ;)
Unfortunately not. Due to the rules of the competition, the game had to be 10 to 20 minutes long, so if I added the second floor it would have been too long. But if it eases your curiosity a little, all that's up there is the other family members' possessions, and Alice moved anything she thought was valuable downstairs. She doesn't like going up there because of her guilt.
