The Imitation Gate: a Turing-test border checkpoint where the sky catches the liars

Short summary

The Imitation Gate is a Papers Please-style deduction game where you examine travelers to distinguish humans from AI using astronomical facts—machines answer like textbooks and get the sky wrong. Built as a single offline-playable ~270KB HTML file with TypeScript/React and a 150-line astronomy engine, it features hand-tuned visuals and real solar data from nine global cities. The game interweaves the Turing test concept with Alan Turing's historical persecution, grounding all verdicts in verifiable celestial mechanics.
