## What is Tidegate?

Tidegate is a quiet, hand-painted island mystery you play with one strange control: the tide.

You wash ashore on Brenn Hollow, a tidal island whose keepers vanished mid-ritual. The moon no longer moves the water — a great brass orrery in the lighthouse does, and it is jammed between phases. Turn it, and the whole island re-floods or drains at once. Low tide and high tide are two different islands sharing one map.

A TIDE YOU CONTROL
Five tide stops reshape every scene at the same time. Dead low bares causeways, cave mouths and shipwrecks; spring high floats rafts and barrels, drives water-wheels, and drowns the paths you knew. Some doors open only at exactly the middle stop. You stop thinking scene-by-scene and start reading the island as one great machine — that cross-scene reasoning is the whole feeling this game is built around.

HAND-PAINTED 2.5D DIORAMAS
Each scene is a set of painted planes at real depth in front of a moving camera, so the world has parallax and weight. The water is a true plane that slides into the scene as the tide rises, swallowing the deeper ground first — the signature mechanic is legible at a glance.

POINT-AND-CLICK, NO PRESSURE
No combat. No death. No timers. Just observation, memory and a handful of genuinely clever puzzles: a drowned carillon whose bells only sing at the waterline, a message walked into the mud years ago that you read by lantern-light at the right tide, a barrel-post you route by opening sluice gates across four scenes, and a cove that runs backwards. In the tradition of classic point-and-click and Myst-like island mysteries.

THE KEEPER'S ALMANAC
A journal that quietly collects the letters and tide-charts you find, and writes gentle, in-fiction hints in its margins once you have been stuck a while — never spoilers before then.

FREE, AND HONEST ABOUT IT
- Play all of District 1 (Harrow Reach) free — around 45 minutes, including lighting its beacon.
- 100% offline. No account, no sign-up, no cloud, no ads, no tracking. The whole island lives on your device.

UNLOCK TIDEGATE (OPTIONAL)
One unlock opens the rest of Brenn Hollow for $9.99: Cannery Rows, the drowned Chapel Shoals, Lighthouse Point, the Tidegate finale, and the Almanac's plain-spoken hint tier. It is one-time and permanent — no subscription, nothing renews — and restores on a new device. The free reach stays free, forever.
