Works on phones and computers

You arrive at a coastal observatory where the clock stopped at 00:17 and explore its dome, archive, signal room and tidal well by clicking glowing objects. A phase instrument flips each room between the Present and its Echo, the minute before, and the two often hold different records. Logs and inscriptions go into a field journal, and you use them to work instruments such as a receiver whose three radio bands must be tuned to one moment. There are four chapters and 13 puzzles, in English or Chinese. Works on phones and computers.

How the creator made it

The creator worked with GPT-6 Astra in Codex on the story, puzzles, bilingual text and JavaScript, going through separate rounds of implementation, browser testing, review and fixes. They used OpenAI's image generator for the painted backgrounds and drew exact clues and diagrams in code so players could read them reliably. The project also makes its WebGL effects and synthesized audio in code.
