Hi Psi,
We appreciate your enthusiasm, but there is no rule against this in the jam itself. The EULA simply states you are legally responsible (not Awful Jams) if copyrights holders come knocking.
To clarify, We will not disqualify a game for having copyrighted material. It's not our place to determine what is or isn't infringing. However if your game is DMCA'd, it will be disqualified and we can't do anything to help you.
Thanks!
