City Courier

Arcade driving: traffic, five deliveries, damage, a time limit and restart.

A complete game with a real win/loss loop. Demonstrates mountable vehicles, a chase camera, deterministic ambient traffic on an inline street network, and a full restart path — plus a command-only victory regression that proves the game is winnable without a browser.

Play it

Play City Courier in your browser. Nothing to install.

Make it yours

The sample ships inside @bendyline/molen-tooling as a template, locked to the engine version you install. Copy it into a standalone npm project (no clone of the engine repository needed):

npx @bendyline/molen-tooling new my-city-courier --template city-courier
cd my-city-courier
npm install
npm run dev

The copy keeps the sample's scene, scripts, commands, checks and headless tests, plus its replay fixture; npm test runs them.
