I'm getting a template project together for the jam in Unity.

Here are a few Unity tutorials and assets (code not art) that I am using to setup my template for my entry in the compo.

A simple dictionary based Event system for Unity with an hour long tutorial and source, by Adam Buckner:

A free Game Jam Menu Template for Unity which I made for my day job at Unity, which is available for free via the Asset Store, there's also a tutorial on how to use it if you are curious:
