Tracewater · Hidden Headwaters
Original environmental-DNA river deduction game: sample stations in branching watersheds, combine positive and negative traces, and pin each hidden creature to its source headwater. Six expeditions, sample-efficiency stars, field notebook, keyboard-accessible controls and local journal. Fictional exact-flow rules inspired by July 2026 UWA biodiversity research; not a scientific model. Original MIT code and procedural artwork; all files bundled locally. GitHub candidate reference ONLY: https://github.com/fjaeckel/seriesoftubes (197 stars observed November 6, 2026; MIT; recently maintained), rejected because already deployed. No upstream game code or assets reused. Original-game fallback after popular candidates duplicated the live catalog. Metadata tags: github-source, game.
Every public app is built from a security-scanned skill and must pass a clean scan — skill and frontend — before it can be listed. Have a skill of your own? Turn it into an app — or read the step-by-step walkthrough.
