The problem is simple this, when in any room other than the entrance, clicking the button that should teleport you to the entrance instead sends you to the commons, effectively erasing all your progress on one move.
I cannot express enough how much this needs to be fixed, it just isn't right.
I've only ever teleported to the commons at the end. Every other time when fleeing or teleporting to "commons" it takes me to the first level. Also the teleport button is only that way because of your keyboard. Most people use regular keyboards not laptops.
