  Game AI competitions are important to foster research and development on Game
AI and AI in general. These competitions supply different challenging problems
that can be translated into other contexts, virtual or real. They provide
frameworks and tools to facilitate the research on their core topics and
provide means for comparing and sharing results. A competition is also a way to
motivate new researchers to study these challenges. In this document, we
present the Geometry Friends Game AI Competition. Geometry Friends is a
two-player cooperative physics-based puzzle platformer computer game. The
concept of the game is simple, though its solving has proven to be difficult.
While the main and apparent focus of the game is cooperation, it also relies on
other AI-related problems such as planning, plan execution, and motion control,
all connected to situational awareness. All of these must be solved in
real-time. In this paper, we discuss the competition and the challenges it
brings, and present an overview of the current solutions.
