Jungle Relic Run
Endless side-scrolling platformer. Double-jump over pits, ride moving platforms, and collect ancient relics. Avoid jungle hazards as speed increases. Offline-first, 100% client-side Vanilla JS with procedural Web Audio API sound effects.
Use Cases
Jungle Relic Run is an endless side-scrolling platformer built for quick reflex sessions. Players guide an explorer through a dense jungle, double-jumping over pits, riding moving platforms, and collecting ancient relics. As the run continues, the speed steadily increases, raising the challenge and testing reaction time. It is ideal for developers, students, and casual gamers who want a fast, keyboard- or touch-friendly platformer break with no downloads, no accounts, and no network requests.
Because Jungle Relic Run runs entirely in the browser using the HTML5 Canvas API and procedural Web Audio API sound effects, it works offline, protects privacy by keeping all state local, and loads instantly on mobile and desktop alike — with zero external assets to download.
How-To
- Objective: Survive as long as possible by navigating the jungle. Double-jump over bottomless pits, ride moving platforms to cross gaps, slide under thorn hazards, and collect golden relics for bonus points. Every meter of safe running adds to your score, and the speed increases over time so difficulty ramps up automatically.
- Desktop controls: Use the Up Arrow, W, or Space keys to jump. You can jump twice in mid-air (double-jump). Use the Down Arrow or S keys to roll under thorn hazards.
- Mobile controls: Tap the on-screen ⬆ Jump and ⬇ Roll buttons beneath the canvas to perform the corresponding actions.
- Rules: Falling into a pit or hitting a thorn hazard ends the game immediately. Rolling under a hazard lets you pass safely. Relics grant bonus points when collected.
- Starting and restarting: Click Start Game to begin. After a crash, the button becomes Retry to launch a new run. Use Reset to clear the current run without driving.
- Audio: Jump sweeps, relic chimes, and collision noises are generated procedurally via the Web Audio API. Click Mute to silence all sound.
Jungle Relic Run is a 100% client-side game built with Vanilla JS and the Canvas API. No server, no network, no uploads, and no external assets — play it anywhere, entirely offline.
