A complete three-heat arcade Red Light / Green Light championship in one self-contained, offline Canvas 2D file. It uses fictionalized, stylized, USAF-inspired training-field visuals and requires no installation or network connection.
Play the game at https://vibezzzcoder.github.io/flightline-sprint (or simply download a copy and play it locally offline)
Every championship runs through all three heats:
- Brake Check teaches acceleration, coasting, and precise stops.
- Signal Run adds fixed-target route gates and score chains: green is Perfect, either amber neighbor is Good.
- Final Protocol combines tighter signals, more gates, faster rivals, placement scoring, and braking precision.
A caught or timed-out heat still awards limited progress points and advances to the next heat. The maximum championship score is 30,000. Bronze starts at 12,000, Silver at 20,000, and Gold requires 25,000 plus completion of all three heats.
- Momentum-based acceleration, coasting, and predictable braking
- Discrete movement across all six lanes, with lateral motion counted during Red
- Standard, Advanced, and Elite available immediately
- Fixed per-difficulty, per-heat seeds for repeatable record attempts
- Pre-announced route gates with fixed green target lanes, amber Good lanes, Perfect/Good/miss feedback, chains, and multipliers
- Original embedded title-screen key art with a responsive accessible menu layer
- Per-difficulty championship, medal, heat, time, and gate-chain records
- Twelve non-colliding visual rivals with deterministic behavior
- Keyboard and mirrored multi-touch controls
- Pause, mute, reduced-motion support, embedded-asset fallbacks, and debug diagnostics
- Embedded visuals and audio with no external runtime requests

- Green target lane: Perfect, 500 base points
- Either adjacent amber lane: Good, 300 base points
- Each successful consecutive bank adds

- Every heat is normalized to 10,000 points
- Failed heats lose completion/time/placement bonuses and are capped at 3,500
Records are stored locally and separately for Standard, Advanced, and Elite. If browser storage is unavailable or blocked, the game safely keeps records for the current session only. There are no accounts, analytics, network leaderboards, or online services.
