Funny thing...
but you should think a little abouth word uses. I mean... Christ? I supose this is a time long before that. And there's no one in hyrule that's christian.
I think it would be a little more funny if you did like somthing... "For Din's sake" or "Oh, Farore's wind" or something like that. I think it would be funnier since then you stick with the Zelda universe instead of bringing up a religion that has nothing to do there. I'm actually surprised that Navi know's abouth Jesus since he's not going to be borned until long time...
Other then that it's great!
