You are likely thinking of Mist which was the previous game he made that has since been completed as that one has the group of people living together in the misty apocalypse.
No. I have seen the Mist you refer to. I had downloaded both Morn games to try them out because the "in game" images where different as was the story discription. I thought they where both by 395games but now I am no so sure. I will have to find my original downloads of both games and find out for sure. I have an external hard drive that I save my game and game update patches on. I just have to dig it out. Then maybe I will figure this out.
