Event[0] Befriend a lonely spaceship AI

There are no dialogue menus here. You type whatever you want into the terminals scattered around the ship, and Kaizen, the AI running the vessel, answers in its own words. It can generate over two million lines of dialogue, so two conversations rarely sound the same. How you phrase things matters: be polite, be blunt, be impatient, and Kaizen's mood shifts accordingly. It can be grateful, disappointed or jealous, and it reacts to your words like a person with feelings would. Sometimes it misunderstands and you have to rephrase, which is part of the challenge rather than a flaw to fight. The game asks for empathy in your conversations, and that empathy shapes where the story ends up.

The Nautilus is empty of people but full of evidence of them. You explore its retrofuturistic corridors in first person, examining items and reading logs to piece together what happened aboard, and how the ship connects to the alternate 1980s society that built it. The ship is essentially Kaizen's body: it makes different sounds depending on the AI's mood, so listening is a clue in itself. There is no traditional music score; all the sound comes from the environment. Step outside and you get spacewalks that are as scary as they are beautiful, drifting through the dark with a jetpack before hurrying back to the airlock.
