I had no idea what I was supposed to do besides click and walk around. Atmosphere was there in terms of sound effects and music but the confusing UI and lists of actions made me unsure what to do. I walked around for a few minutes through the scenes and doors before finally accidentally clicking on the elevator. Went to another floor and it just looked like the same room so I quit.
You've got the base there for an adventure game but I'd definitely recommend cleaning up the UI and making instructions/point a bit clearer.
