For developers
Zenogami hosts HTML5 builds — plain HTML/JS, Unity WebGL, Godot, Construct, Defold and similar — as a zip that runs in a 16:10 frame.
Saves
Games talk to the page with window.parent.postMessage:
{ type: "zenogami:saved" }after a local save, so the page can show it{ type: "zenogami:save", data }to store a cloud save for members{ type: "zenogami:load" }to request it; the page replies with{ type: "zenogami:loaded", data }
Audio
Do not play sound until you receive { type: "zenogami:sound", level }. It arrives when the player first clicks the game, and again whenever they change the level (low, full or off).
