It is a game... which integrates strategy, puzzles and philosophical questions into a world which explores a range of commonly (or less commonly) held views about death, belief and science.
The game takes the player on a metaphysical journey, recording their interactions in the world to reveal their attitudes towards mortality. These views are presented alongside their friends and some of the most important thinkers of our time, such as Gandhi, Descartes and Einstein.
...The ultimate prizes are the Death Objects, ranging from a memorial diamond to a human heart, which deepen a player’s contextual knowledge of death and help them progress through the game.
