I just wanted to give everyone a heads up. Yes, this game is still in progress, but a different kind of progress. I am in the process of porting this game from XNA to Unity. Unfortunately, XNA has just too small of a target audience for it to be realistic for me to use. PC is good to make games for, but XBLIG, not so much. With Unity, a whole new set of options for publishing opens up.
That being said, I am essentially remaking everything in Unity. There are a few options for shortcuts, but ultimately it is going to take some time, and I will try and post what I can as I go.
