Nice build. I'm not so sure that I like the idea though, my problem is that you could replace the UPS guy with just some normal person and there wouldn't be any difference, I'd like to see a scene in which it's important that the hero is a delivery man.
Very nice! If I were in this division, I would have gone with something very similar (my idea was a pizza delivery guy going to the moon to make a delivery to some hungry astronauts). The Big Dipper feature is really cool.
