The game is played from a first-person perspective with the direction in which the player is facing controlled by the mouse. On each static screen, the player is free to look around 360o. The game's interface is very simple; there is no HUD, instead the player has access to an inventory in which all items are stored. From the inventory, the player can also access objectives, review dialogue and examine any documents they have acquired.[9] To speak to people or interact with objects, the player must click on them with the pointer. As the player moves the pointer around the screen it can change to an arrow (meaning the player can move in that direction), a magnifying glass (meaning the player can inspect something in more detail), a cog with a red line through it (meaning the player must use an item on the object), a cog without a red line (meaning the player can operate the object without using an item) or a hand (meaning the player can pick the item up). When the player clicks on a person to whom they wish to speak, a list of conversation topics appear on screen. When the player picks up an item, it is automatically put into an auto-holder rather than the main inventory, and must be transferred manually from the auto-holder to the inventory screen. This allows the player to sort the inventory in any way they wish.
