assets & saves

include assets in your game package and use the saves API to store player progress with their consent.

assets

game.assets.get(name) returns a packaged data URL. supported formats are PNG, JPEG, WebP, PCM WAV and WOFF2. the package digest covers every byte. games cannot fetch arbitrary URLs or account APIs.

add saves to your manifest capabilities to use read(), write(version, value) and delete(). writing a save opens a consent prompt and allows up to 16KB per player per game. read returns the stored schema version so you can migrate older data. saves are included in account export and deletion. the server stores match state separately.
