Papa Sangre, a game I helped make, has been analysed by Andrew Hugill at De Montfort University in terms of its audio composition. It's delightful to see something you made through such an academic lens. The following comment, a wonderfully formal admission of fear, reminds me of M.R. James.
The sense of danger is surprisingly realistic, especially given the compromises in verisimilitude that are of necessity made by the game’s design. This sense lasts beyond the game, at least for the present author, who experienced a rather unpleasant nightmare that was clearly derived from the gameplay.
