Moving from place to is done by clicking on the name of the doorway you want to go through. They are shown in italics if closed or describe where they lead if open.
You can also use the go command to name where you want to go (if you can see one that is) go to the exit
Or, if the door is facing a specific direction, just type the direction eg: north
Or to leave a room with an exit, type exit
Remember, if you get lost type start to teleport back to the find: [open field] where you started your journey in cow.
You may find the map, radar or detect life useful.. but maybe not.
