We're building ▇▇, an analog RPG about field cryptography and terrestrial reconnaissance, featuring the in-game handheld field cipher, garrbl, a bantamweight authenticated ARX-based Lai-Massey block cipher designed in the koobifora cryptographic design language, inspired by the evolution of hominin biomechanics and the camel-based trust system of northern Kenya's Gabra people.
