A tour of the complex and interlocking design challenges involved in making Gorogoa. What were the basic themes and the inspiring fantasy that gave rise to the core mechanic? What were the narrative challenges involved in telling a story without language, in which time and space are broken into fragments and constantly recombined? What were the artistic challenges in a game where visual design and puzzle design were hopelessly tangled together? The talk will answer these questions through a high-level look at the meaning and formal properties of the game's mechanics, as well as detailed accounts of how individual puzzles and scenes were constructed.
