I was confused at first: "Load configuration file?" Well, okay, once I figured out how to start a game, it seemed like a database of little factoids, seemingly unrelated to each other. Then there were the personal notes, which made the unseen narrator an NPC in its own right. Endling tugs on your heartstrings because the triviality of some of the 'files' contrasts starkly with the gravity of the disaster the narrator alludes to.
Even though there is no story in the traditional sense of the word, even though it basically is a bunch of factoids, it is elegantly written, carefully constructed and moved me to tears.
