Is this theme really all you could come up with?
This isn't an annual game jam, so I think the name fits quite well. The jam is a one time thing that focuses on the use of loops. I honestly can't think of a better name, than "Looped Game Jam" to describe the jam.
But then again, if you don't like the theme, just don't participate. I don't see anyone forcing you to take part in this.
