Bury My Heart at Towlr Mountain
BuryMyHeart is a certain kind of game, known as a Towlr. Among several requirements, Towlr must not give the player any indication of what goals the player is trying to achieve. In other words, the purpose of a Towlr is to figure out the goals of the game (and then complete the game, of course). Read the full Towlr manifesto to see all the requirements.
