Congratulations man! I really wanna play this!
Like seriously, what you're doing is really awesome and deserves more exposure. Have you ever thought about making a game out of this, and not a mod? Like a stand alone thing, or even making a small indie game? Isn't this engine open source now?
I love the fact that you're going for that very harsh pixelated look like minecraft, there really isn't enough games like that. Really shows your head is in the right place!
