Well… that was a whole lot more difficult than I expected.  I thought my scope was reasonable… turns out, nope.  When I realized I was behind schedule, I had to get ruthless about cutting features.  Enemy pathing?  Nope, they can fly instead now!  Do any modeling work?  Nope, grab those free assets on the Unity Asset Store.  Think you are done when it looks good in Unity editor?  Nope… better double check that webplayer export… (framerate difference caused issues).  I submit.
