Reading the Rules of 'Baba Is You'


Arvi Teikari, developer of the puzzle game Baba Is You, describes how the game's unique sentence-based rule system was implemented and what kind of iterations and obstacles it went through over the development of the game. The talk concentrates on the technical aspects of turning physical items in the game world into sentences understood by the game logic, as well as building a data structure that supports this kind of functionality. The talk will also touch the topic of the realities of developing a complex puzzle game using a non-programming-based game-creation tool and the lua scripting language.
