I was playing a Mario game where every “screen” moved to another screen projected onto the wall. I eventually reached a point where I was on the screen next to the door and was unable to progress unless I continued playing in the next room over. I opened to door into the hall and saw that the lights in the neighboring room were already on. I later heard a flush of the toilet from down the hall. Apparently my mom was reading in the room that only contained a white wooden table and chair under the yellow light. She said I would be able to progress the game if I reconnected the projector to my own computer without needing to switch rooms.
