This achievement requires you to make a wrong move, thus dying whilst in the Bedroom (the room where you have to jump through the closing gap in the wall).
This must be done on Hard and you must move either Left or Right as moving Down or Attacking will trigger an alternative death sequence.
Whilst playing Arcade Mode the Bedroom scene will always be either the first, fourteenth or twenty seventh room, remember that if you die in Arcade Mode you move to the ext room in the sequence.
