I just published a version where the elevator and Francesca's cutscenes crashing are fixed, was pure carelessness on my part that they got published, apologies. As for getting stuck, that's a known issue, but would require a significant overhaul to the way the movment works in 3D which I am simply not able to do right now, though it is a priority. I don't have a fix for that other than returning to the main menu, your progress saves every time you enter a room, so you lose nothing by continuing there.
