Level-Based Pixel Dino Game

I’m building a small browser game that brings the familiar “offline dinosaur” concept into a richer, level-based experience, playable exclusively on desktop. Everything needs to run in plain HTML5, CSS, and vanilla JavaScript so users can simply open index.html and start playing—no installs, loaders, or external libraries.

Core requirements
• Gameplay: Instead of an endless runner, each stage has a clear start and finish with increasing difficulty, unique obstacle patterns, and a simple score system.
• Visual style: 8-bit, classic pixel art. Think retro consoles—limited colour palette, chunky sprites, crisp audio beeps for jumps and collisions.
• Controls: Space or ↑ to jump, ↓ to duck. Please keep input handling responsive at 60 fps on Chromium and Firefox.
• Assets: I’ll need all sprite sheets, background tiles, and SFX in organised folders so I can tweak them later.
• Code: Commented, modular JS (ES6) and clean CSS. No frameworks; feel free to use Canvas or SVG as long as everything is bundled locally.
• Winning condition: Reaching the finish flag without losing all three lives; display a simple end-of-level screen with stats and a “Next Level” button.

Deliverables
1. Full source code zipped and ready to run offline.
2. Short README outlining file structure and how to add new levels.
3. A demo GIF or WebM under 10 MB that shows Level 1 from start to end.

I’ll test on latest Chrome and Firefox; acceptance is a smooth, bug-free run through three sample levels at 1080p. If you’ve built pixelated platformers or Canvas projects before, I’d love to see a link. Show More
