1. in the "error" note, the capitalized letters spell out THEODORE, the name of the man on the business card. Interesting!
2. also in the game files, in a folder titled saves, there's a file titled "persistent". It has a lot of text in chinese characters and some random symbols. Google translate got very confused!
Later, when I looked back at the file, it was garbldygook that I don't know how to decode.
Someone else should try to decode it, they might have more success than me!
