              Doors are in front of you. Some are locked and require keys. Items are picked up automatically when you step on them.

    About state in URL
    
            
    
              The fragment #… contains a base64url-encoded JSON state. This is why copying the URL reproduces your exact game state.
              The server never sees the fragment.
