Man you're going in the right direction to do quintessence of survival. I played today something about 4 hours. it Is for now grate :D
i didn't find any buggs or something but i have some ideas. U can add mb gun powder and to combinate with scrap it will make sm guns. This game needed more tools to defend. Hmm mb some bows or crosssbows. sry 4 my english :P for now good way to do such a great survival game. Nice job.
