Single-file JavaScript games

File format

The importer statically validates metadata and restricted capabilities. It stores source as an editable script asset without executing it.

DeltaGame.define({
  metadata: {
    name: "Orbit Dash",
    description: "A tiny orbital runner",
    version: "1.0.0",
    apiVersion: "1"
  },
  start(engine) { engine.scene.spawn("player"); },
  update(engine, dt) { /* game loop */ }
});

Compatibility

Generic browser scripts are not promised automatic compatibility. Network calls, direct storage, Node APIs, eval, and Function constructors are rejected; migrate those capabilities to the Delta bridge.
