Comet Courier Mobile Game Kit is a touch-first arcade delivery game starter built around a simple original loop: steer a courier comet through shifting gates, collect parcels, and spend momentum before the route collapses. The package includes a playable HTML5 demo, responsive touch and keyboard controls, game-state JavaScript, a mobile layout guide, tuning notes, and a sample level. It is designed for rapid prototyping and can be adapted into a mobile web game or used as a mechanic reference for a native build. All names, screens, code, and sample content are original and contain no third-party brand assets. License: one buyer only; non-transferable; no resale, redistribution, sublicensing, marketplace upload, standalone client delivery, or competing derivative product.
