About The Project

Snake Game is a zero-dependency, modern web implementation of the classic arcade title, engineered with native browser standards to deliver deterministic gameplay, zero-allocation rendering, and fluid performance without framework overhead.

---

Live Demo

The production build is continuously deployed via GitHub Pages:

Direct Access: https://ramazancetinkaya.github.io/snake-game/

Optimized for instant execution in any modern browser without installation or local setup.

Features

• High-performance game loop utilizing requestAnimationFrame with precise timestamp delta calculations for deterministic tick pacing across varying refresh rate monitors.
• Double-buffered input FIFO queue preventing illegal 180-degree self-collisions when multiple directional keys are struck rapidly within a single physics cycle.
• Zero-allocation DOM entity recycling pool (domEntities) mutating hardware-accelerated CSS translate3d transforms, eliminating layout recalculations and garbage collection pauses.
• Real-time procedural audio synthesis built on the Web Audio API with a 3200Hz biquad low-pass filter (Q: 0.7) and soft gain envelopes to prevent acoustic fatigue.
• Strict 100dvh viewport containment with dynamic CSS variable bindings (--grid-size, --cell-size) ensuring zero accidental page scrolling on touch devices.
• Dynamic scoring algorithm featuring escalating combo multiplier streaks, countdown windows, and floating point indicators.
• Special consumable foods including Golden Star (score multiplier and combo window extension) and Chill Berry (pace deceleration effect).
• Tiered progression system with 15 granular achievements tracking single-run triumphs and lifetime milestones.
• Customizable snake aesthetic palette themes (Obsidian, Emerald, Cobalt, Amber, Crimson, Sage) stored persistently in localStorage.
• Comprehensive session management with anti-tamper state invalidation when core gameplay difficulty parameters (speed, grid size, wall mode) are modified mid-run.

Controls and Shortcuts

The game engine provides full input parity across desktop keyboards, hardware peripherals, and mobile touch surfaces.

Action	Primary Shortcut	Secondary Key	Touch / Mobile Interface
Navigate Up	ArrowUp	W	D-Pad Up / Upward Swipe
Navigate Down	ArrowDown	S	D-Pad Down / Downward Swipe
Navigate Left	ArrowLeft	A	D-Pad Left / Leftward Swipe
Navigate Right	ArrowRight	D	D-Pad Right / Rightward Swipe
Pause / Resume	Space	P	Center Pause Button / Board Tap
Sound Toggle	M	-	Settings Segmented Switch
Settings Modal	O	-	Header Settings Button
Achievements Modal	T	-	Header Trophy / Sidebar Row
Help & Rules Guide	H	-	Header Help / Start Screen Action
Quick Restart	R	Enter (Game Over)	Modal Restart Button

Note: Directional inputs are subject to an active turn buffer. Submitting a reversal command against the current velocity vector is discarded by the engine to safeguard the snake from illegal self-annihilation.
