✨ WHAT MAKES THIS SPECIAL
────────────────────────────────────────────────────────────────────────────────

This isn't a tutorial scaffold or a half-finished demo. This is a complete,
polished game that runs perfectly in Chrome, Firefox, Edge, and Safari — on
desktop AND mobile.

• 5 Themed Levels with distinct environments:
↳ 🌿 Level 1 — Green Meadows (gentle intro, rolling hills, floating platforms)
↳ 🪨 Level 2 — Stone Caverns (cave ceilings, lava spike pits, tight corridors)
↳ 🏜 Level 3 — Sand Desert (dunes, cactus decor, aerial spike corridors)
↳ 💜 Level 4 — Purple Twilight (floating island chain, stars, no ground!)
↳ 🔥 Level 5 — The Gauntlet (mixed-terrain final boss level, ember effects)

• 4-Material Auto-Tile System (grass, stone, sand, purple) — tiles visually
self-connect with correct corners, edges, and centers automatically.

• Animated Pixel Art Sprites — idle, walk, jump, and hurt states for the player;
animated slime enemies with patrol AI and stomp mechanic.

• Parallax Scrolling Backgrounds — each level has a unique parallax sky/cave/
desert/twilight background that adds real depth.

• Collectible Coins with physics bobbing animation + sound effects.

• Spike hazards, gaps, and platforming challenges with difficulty curve.

• Star Rating System (1–3 ⭐) based on coins collected per level.

• Level Select Screen with locked/unlocked states and best-score persistence
via localStorage.

• Lives System (3 hearts), invulnerability flicker on hit, bounce-off-enemy stomp.

• Mobile Touch Controls — left/right D-pad + jump button, works on phones.

• Animated Main Menu with floating particle canvas background.

• Loading bar with asset preloading for smooth first-run experience.

• Web Audio API sound effects (jump, coin, hurt, win).
