I played on PC and reloading did the thing I believe. Sometimes it looks like you walk behind uhhh art I guess.
Let's see if I remember, I believe not being able to get a respons from one or two of the girls that maybe just aren't in the demo? yet, felt as if it wasn't working.
I'm unsure if I remember it right, but I think the first time the secretary suddenly stopped reacting to clicking.
The other thing I thought was a problem was probably only the coffe maschine.
Not sure if I got to use whatever stuff I got out of the uhm maschine (with the money)
oh and the pingpong felt bad, I somehow got a reaction out of the game for a while but I have no real control over what happens there.
