Having the same issue, I can sometimes move between rooms, sometimes not. I can pick up items and sometimes put them down. Teleporter and all the buttons around it dont appear to work at all.
I've found that I often cannot let go of things unless I first switch them between hands. I've also found that buttons only work if you press them very lightly and not in to far. Right now I'm hopeful that the release in a few days will greatly fix things because as it stands the game is next to unplayable. I'm amazed it has been let out into the wild in this shape considering the developer is very well-established.
