My contribution is called “The Children of DiscoDroid” and takes place on a dance robot drifting through space. A miracle has happened and life has been created on the robot’s body (yes, it is inspired by a Futurama episode).
Every creature is sensitive to music and can be controlled that way.
You can actually test the current version (and all future current versions) here:
My LD48 Entry on Wonderfl (where I compile all code so it might not work if you try it later)
At the time of writing, you can just walk around but that will change soon. You will later be equipped with a stereo that you can play music with that. When you do that, it makes the bad guys dance and follow your moves. In that way you can defeat other bad guys or lure them into holes or other nasty places.
