After watching Pixel Prophecy's ludum dare videos almost to a religious degree, I finally decided to try it for myself. I started using Unity... 3 days ago, so have basically 0 Programming experience,- So am I completely in over my head?

Yes. Is this a great way to get yourself out of your comfort zone and learn some useful skills? Also Yes.

So even if I don't make anything resembling a game the things I learn on the way, will be more valuable then the product after-all.
