I have gone ahead and updated my October 2015 Mega Jam game with a few new features like Story Mode and full Gamepad support and I am tossing it all up here =) The packaged project is below to download and play as well as a link to the public GitHub repo for the source.
Most of the source is not commented and it is pretty rough as this is about 60 hours of work for the jam.
Have fun. This is do what you want with what I provide here.
