You wake up in the world, what is being called world between life and death. It is up to the people themselves to fight for survival. But this world isn't empty, it is magical world and it is owned by someone who is being called death. Apparently he isn't god of this world and can only manipulate everything. So you escape from him but at the same time you go through your dark past, so you would understand, why and how did he end up there.
In short, this is a really great map. Unique and fresh. But it has a certain lack of seriousness that doesn't always work in its favor, and there are a LOT of immersion breakers. Overall though, it's pretty good! Looking forward to chapter 2 :)
