While the core story is covered via cut-scenes, the background can be understood in more depth by finding various collectibles which remain in Rosemary's inventory for more detailed overview. The game includes certain quick-time events when fighting enemies, and failing at any of them means certain death. The estate is very dark and to more easily explore the estate Rosemary carries a pocket flashlight which just about lights what's directly in front of her, but also makes her that more visible to the enemies hunting her. Hiding places are a way to definitely avoid confronting someone, unless they saw you enter the hiding place, but while in hiding spot (i.e. in the closet or under the bed) with the enemy standing in front, the pointer appears which need to be kept inside the designated circle in order to remain hidden.
While the game uses shoulder camera by default, the player can walk in any direction and controlling the camera needs to be done separately as the camera won't remain locked to character's back if Rosemary is walking left, right, or toward the player. The shoulder camera can be switched between left and right side, however, to provide better angle and view which comes useful when looking behind the corner. The game uses auto-save feature only at specific points in the story, and otherwise requires the player to stand in front of a mirror with the pendulum clock in order to save the game progress, and there are only a handful throughout the entire estate. Clearing the game unlocks extras accessible via main menu, most notably making-of character and setting artwork.
