The intention, and link to “Body”, is using the different phobias/fears in the design of each of the three environments to raise a player’s heart rate. This physical bodily reaction of a rising heart rate to audio, visual and physical elements in these levels is directly disadvantageous to the player as it creates a negative feedback loop where the game gets ‘harder’ the more ‘stressed’ they get. The only way to break this loop, and regain control of the game’s difficulty level, is for a player to breathe and to calm themselves down whilst playing.
