What a wonderful game! I really adore games where you root through diegetic computer systems to learn more information (ex: Uplink, Hypnospace Outlaw, most imsims, etc), and this is an amazing example of how that can be done in the RenPy engine. In particular I found the use of the main menu and persistent variables to save progress to be really clever design decisions.
The way the story unfolds is also really rewarding, I appreciate the use of different types of media to help paint the whole picture.
