#DHSeaDev — Chrome MV3 — Isometric Puzzle
Emberkeep — Mountain
Emberkeep — Mountain is an isometric light puzzle in which a small fire climbs an impossible mountain to light what went dark. No falling, no failing, no hurry. A standalone sequel to Emberkeep, free in your browser.
The game
Ten chapters
From The First Light to The Beacon, each chapter a lattice to route the light across. The mountain does not entirely agree with itself.
No falling, no failing
There is no death and no timer. The only question is where the light goes next.
The ones you meet
The Watcher, The Gardener, The One Who Waited — twenty named figures on the way up, each with something to say.
Standalone sequel
Same ember, new geometry. You do not need to have played Emberkeep, though it helps to have met the fire.

Questions
Is Emberkeep Mountain free?
Yes. It runs in the browser at play.dhseadev.online with nothing to install and no account; the Chrome extension build it started as is not on the Chrome Web Store.
Do I need to play Emberkeep first?
No. Mountain is a standalone sequel with its own chapters and its own geometry.
Does it collect anything?
No. It makes no network requests of its own; the arcade’s shared play counts and star ratings are the only thing that leaves the page, and they carry no account or identity.
