Brenn Hollow · the keepers are gone

The keepers vanished mid-ritual. The tide is still waiting.

Brenn Hollow is a tidal island whose keepers disappeared in the middle of a rite. The harbor beacons are dark, the bells are underwater, and the great brass orrery that sets the tide is jammed. You wash ashore at ebb with nothing in your hands and a letter in the sand.

Turn the orrery and the whole island drowns or drains at once. Read the mud ledger at half tide, ring the drowned carillon at its waterlines, chart a cove that keeps a contrary clock. Relight all four beacons, find the second orrery, and open the Tidegate to learn what the keepers were trying to do, and why they never finished.

Low tide and high tide are two different islands sharing one map.

One control, five tides, every scene at once

tide puzzle

One control, five tides, every scene at once. Dead Low, Ebb, Half, Flood, Spring High. The orrery sets the tide for the whole island, so a sluice opened in the cannery can finish a puzzle at the chapel. Far planes drown first.

Questions

Tidegate, in a browser and on a phone

Is Tidegate a Myst-like?

Yes: a first-person-feeling point-and-click on a mysterious island, hand-painted, with puzzles read from the world and documents rather than told. One idea is its own: the tide is the only control.

Can I play the island puzzle game in my browser for free?

Yes. Harrow Reach, the mud ledger and the first beacon are free in your browser and on your phone. The other three reaches and the finale are one purchase.

Is there a Myst game for iPhone or Android?

Tidegate is on both stores and in the browser. On the phone it plays offline; the browser edition saves in your browser.

What is the tide puzzle?

A brass orrery sets the tide to one of five stops for the whole island. Everything responds at once, so the same scene is a different place at low and high water.

If I unlock it on my phone, is it unlocked in the browser?

Yes. Open the app, choose Play in your browser in Settings and scan the code on this site. Your beacons, journal and the unlock come across.

If I unlock it in the browser, is it unlocked on my phone?

Sign in with Google before you pay, then scan the code from your phone once; the unlock is on your phone for good.

Are there timers, combat or a way to die?

None. You can leave a puzzle for a week and come back to the same tide.
