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.
Pretty good, not the best one out there but it has a certain charm to it. Certainly some nice variability with puzzles (not the same old key/door puzzles over and over).
Overall, the main flaw in my opinion is that it isn't presented as serious as it maybe should have been (death continuing to say "Epic" and "Awesome" or when he says "by the way" it is shown in the subtitles as "btw"). Also (when you play as the detective) you're missing some welders on the stairs and the detective doesn't have subtitles when he speaks.
tl;dr Good story but some errors (probably from rushing it out to meet a deadline), get past those and it earns itself a 7/10
