Since no official "v1.0.13" patch notes exist in major public archives (the game's notable PC patches ranged from 1.0.0 to 1.0.6 and later console updates), I will interpret your request in two ways: first, as a , and second, as a critical essay on the game’s themes , using the version number as a lens for its iterative perfection.
