One problem, your AI. It's rediculously retarded.. I can't beat Challenge # 4 because the shield and sword don't respond well.. not only that.. maybe you should've made the sword a jackhammer.. that way it would've seemed more realistic... and a bit easier seeing as the AI is to stupid to comprehend where to go..
Not only that, but I glitched on day 19, where I killed everyone but my for kept getting damaged, so now theres nothing I can do.. I'm just sitting there with no fort and nothing to kill.
