The User Interface in Luigi's Mansion 3 is clean and informative. In the top-left corner, you'll see Luigi's health bar, represented by hearts. The top-right displays your current floor and the number of Boos caught on that floor. The bottom-right shows your current Poltergust attachment (Dark-Light or Suction Shot) and its charge. Keep an eye on these indicators to stay prepared for any ghostly encounters.
