The first prototype for GrACE used the metaphor of an octopus trying to find food through a system of underwater pipes. A version of that game is archived for playing online.
More recent prototypes have used the metaphor of a mouse and bunny needing to work together to navigate a system of underground cracks and rocks to find vegetables. This version will be available for playing online soon!
We are currently working on an updated version of GrACE, fixing bugs and adding features based on feedback from our early prototyping sessions!
