While this uses copywritten stuff, it's NOT assets as in from a video game, so it is sort of a gray area. The rule as it was written was to avoid theft from video games and this one was really, really clever. So I'm going to allow it to remain in the jam, but if enough people come to me with issues, it may get disqualified.
That said, I really did enjoy the humor of this one. Very short and sweet, but easy to play and actually had a decent little story to the whole thing. Not bad at all!
