About

Change a garden in 1996 and watch the consequences unfold in 2026. Redirect water, grow a bridge from roots, and guide light home across six short puzzles. Built with GPT-6 Astra in Codex. Free to play in your browser, with no sign-up or runtime AI calls.

Attention & discussion velocity

Not enough snapshots yet. Run the snapshot worker every 15 min to build the time-series.

Performance

A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
