Ideally you should build the game and upload that as well so people can easily play it.

However, this is a unity project, so I loaded it into my unity, and it is an extremely simple game of navigating a ball past obstacles to get to a goal, and that's it. It uses simple Unity primitives with a material colour on them.

There is no sound, or story, and it has nothing to do with the game jam theme.

Where's the .exe?
