It allows to run faster to avoid bullets or enemies and jump further Shadow run activates when holding SHIFT(keyboard) or B(gamepad). Shadow run uses stamina Balance *new sounds for swords and bows *stamina generation increased *reduced resistances for nest-like mobs. *several notes added to starting level *cutscene is much faster in starting level *Blacksmith is now interactable with E(keyboard) Bug fixes *fixed bugs when using bow *fixed bugs in starting level * some other small fixes
