Line Up: Dots | HTML5 Space Puzzle Game

Line Up: Dots is an addictive HTML5 space-themed puzzle game built with pure HTML5, CSS3, and vanilla JavaScript — no frameworks, no backend, no database. Players trace a line between scattered numbered stars in ascending order, dodging asteroid fields and riding portals to reach every dot before the clock runs out.

With 50 handcrafted levels spread across six escalating difficulty tiers — Training, Focus, Rush, Chaos, Mastery, and Finale — Line Up: Dots grows from a gentle introduction into a genuinely demanding sequencing puzzle. A countdown timer on every level, a 3-star rating system, and a limited-use hint system keep each attempt tense and rewarding.

Being 100% client-side, Line Up: Dots runs anywhere a browser does — a static website, WordPress page, portal, kiosk, or wrapped inside a WebView for iOS/Android app stores — with zero server-side dependencies, zero setup cost, and zero ongoing hosting overhead.

REQUIREMENTS No server-side language or database is required. Line Up: Dots runs on any static web host (Apache, Nginx, GitHub Pages, Netlify, S3, cPanel) or directly from local disk. A modern browser (Chrome, Firefox, Safari, or Edge) with JavaScript enabled is all that’s needed to play.

Full documentation is included, covering installation, a complete feature walkthrough, developer/architecture notes, and a step-by-step guide for customizing both the visuals and the core game logic — sequencing rules, obstacles, portals, timing, and difficulty curve.
