I usually have a stable idea at least 3 hours into the compo, but this time I just have a huge list of ideas with nothing I really want to do.  After sleeping over it I think I generated a fairly decent idea, though!  So the first 3 hours I spent getting base code down and A PARTICLE ENGINE!  I’ve never done particle engines before, and now I see why people say they are so fun LETS GET WORKIGN!
