Description

AI generated. Loopline Rally is a short run arcade racer built around improving a line through the same circuit. Choose Saltwater, Mesa or Afterdark styling, a named seed and either a one lap Sprint or three lap Grand loop. Each circuit uses twelve ordered gates, so skipping a later gate does not advance the lap.

The vehicle model separates forward speed from lateral slip. Braking, handbrake, off road grip and boost change how the car handles. Checkpoints replenish boost. Recovery returns the car to the previous checkpoint with a five second penalty. Original scenery, follow and overview cameras, and a live minimap make the route readable.

Complete a race to prepare a local ghost file, then import it for the same seed, circuit and mode. Save an active race or prepare a PNG lap card. All graphics, circuits and optional synthesized effects are original. No account or online racing service is required.

Setup requirements

Open index.html or serve the folder with any static web server. Select a seed, circuit and lap mode. Start the race and wait for green. Auto throttle is enabled by default; steer with A and D or arrows. Save before closing. Run node tests.cjs and node balance.cjs for model checks.

Dependencies and ongoing costs

A current browser with JavaScript and Canvas 2D is required. Optional sound uses Web Audio. No external runtime library, paid API, account server or recurring service is required. Node.js is used only for the included development checks. Static hosting can be supplied by the buyer; none is purchased or bundled.

Known limitations

This is a top down Canvas browser arcade racer, not a native driving simulator or a multiplayer service. The vehicle model is simplified and the speed display is an arcade indication. Three circuit styles share a seeded loop generator. Races are intentionally short; scripted three lap tests completed in about nineteen seconds. Gates validate local progression but are not server anti cheat proof. Local ghost files can be edited and must match the same seed, circuit and mode. Active race saves and imported ghosts are separate files, each limited to 1 MB. Physical touch hardware, extended keyboard only play, gamepad and broad device performance were not independently certified. There is no automatic persistence or cloud account. AI generated disclosure appears in the game and listing.
