I agree. I didn't know about this dark period in Chinese history, though many parts of the World including Europe (historical article) and North America (eg. - The Donner party incident) have each had their horrific accounts of cannibalism during extreme times of food shortages. This VN attempts to re-create, with its wonderfully detailed illustrations, moving background soundtrack and rich storyline, the events during this difficult period and how people managed to survive with or without having to succumb to such a desperate process, so that player can develop an idea, first-hand, of what it was like to have gone through such an difficult experience (Of course, that is but one of the themes of this game which includes revenge, involuntary servitude and more).

Here's another interesting thing - Not to be a little OCD but it seems that Steam displays the languages supported in the Language Support notification in different order according to the region where a Steam user may be located. When I visited the Steam page for this game, I noticed that the Japanese language was listed last rather than second. It's very curious as to why Steam would do that.
