You survived the Apocalypse, but what will you do, when you are scared, alone, and your hope is dead?
I really liked what you did here.
Although it's too short, the feeling "loneliness" is pretty impressive and you've managed to create that atmosphere.
Some of the technical details were a bit bad. Like invisible walls and visible walls that we are able to walk through them. Very slow walking (of course for the atmosphere, but even running is too slow), narrow doorways that I barely managed to get through. And there are parts might be frustrating for some players. I died after jumping from a windows and game sent me back to the point where I reached to the town.
Other than that, it is really good. Due to story, making it longer might ruin the atmosphere.
Thanks.
