The Misdirected
Tide.

A ferry departs. A tide chart vanishes.
Four records. One account that fits.

The last post has closed, but envelope M17 never reached its collection shelf. Four surviving records tell a quieter story. Piece them together before anyone calls it a theft.

FROM A LARGER COASTLINE

Some letters arrive late.
Others change a town.

The planned main case, The Last Collection (working title), follows an altered signal record and a missing packet through one storm-bound evening. A 45–60 minute design for one or two adults.

A NOTE ON THIS EDITION

A case in progress.

This is an original browser playtest prototype. The mini case is playable; the main case exists as a design draft. Titles are provisional.

Designed for English-speaking adults playing alone or together. There is no violence, timer, account, payment or live AI. Difficulty, play time and commercial demand have not yet been tested with people.

Your notes, opened exhibits, hints and findings are saved only in this browser when storage is available. Select The Brinewick Post title to return home without losing progress, then choose Resume the case file to continue. Restart asks for confirmation before clearing this case’s progress. Another browser or origin has separate progress.

Generative AI was used substantially for this prototype’s code, visual design and fiction. No AI service is called during play. During a PlaytestCloud session, screen activity and spoken commentary are recorded by PlaytestCloud; this includes anything typed into the scratchpad. Follow the service’s recording and consent instructions and avoid entering personal information.

Keyboard: Tab to move, Enter or Space to activate buttons, arrow keys to choose within an answer group. No dragging required. Evidence stays available after solving.
