MAXIMUM UNCHAINED OVERKILL • 150BPM SYNTHWAVE • ZERO INHIBITIONS • FULL GAS
RAINBOW FEVER. 76 segments, 27x combo, 280% engine speed, walls turned off.
Forget whatever boring, beige, 1997 Nokia snake game you played in middle school. HYPER-SNAKE: APOCALYPSE SINGULARITY is a dopamine-fueled, retrowave-blasted, screen-shaking, thermonuclear arcade acid trip that turns a simple grid game into PURE UNFILTERED CYBERPUNK CHAOS.
Built into a single, self-contained index.html file with zero external JS libraries and zero image assets. Everything—the audio synthesizer, drum sequencer, particle physics, 3D warp grid, and bloom shaders—is generated raw on the metal in real time.
Nothing here is a sprite. Nothing here is an MP3. Every pixel and every sound is computed from scratch, every single frame, while you play.

Five seconds of it. Laser cross-beams, a nuclear whiteout, and Fever kicking in.

No MP3s. No WAV files. No network lag. Not one byte of recorded audio ships with this game.
- 150 BPM Darksynth Drum Machine: Real-time synthesized kicks, snappiest noise claps, and open hi-hats.
- Rolling Acid Bassline: Dynamic low-pass resonant filter sweeps that crank up and distort as your combo grows.
- Sound FX Synthesizers: Procedural white-noise explosion filters, FM laser sweeps, ascending singularity risers, and victory fanfare chords.
The soundtrack reacts to how well you are doing. Rack up a streak and the filter opens, the distortion bites and the whole mix gets meaner. The game is scoring itself while you play it.
- ⌨️ Keyboard: Arrow Keys or WASD to steer, Space / Enter to restart, F for fullscreen.
- 🎮 Xbox / Bluetooth Gamepad API:
- D-Pad / Left Thumbstick: Full 4-way navigation with analog deadzone filtering.
- A / X / Start button: Start game / Instant Respawn.
- Dual-Rumble Haptic Feedback: Dynamic low/high-frequency motor vibration triggers on eating, nuke detonations, laser bursts, black holes, and deaths.
- 📱 Touch D-Pad: Automatic on-screen touch overlay on phones & tablets.
Plug a controller in and the pad rumbles differently for every kind of death and every kind of pickup. A nuke is not the same handful of vibration as a laser.
The board grows to fill whatever room it has. The column takes the viewport height, the chrome takes what it needs, and the board absorbs everything left over, so there is no magic reserve to get wrong when the title reflows or the touch d-pad appears.
Hit FULL in the HUD (or press F) and it reclaims the browser chrome too. Same 20x20 grid at every size — only the pixels get bigger, never the board. A phone and a 4K monitor play the exact same game.
| viewport | board |
|---|---|
| 900 x 613 | 449px |
| 1280 x 713 | 530px |
| 1920 x 1093 | 884px |
| 2400 x 1413 | 1100px (capped) |
The canvas keeps a fixed 540x540 backing store and CSS stretches it, so every draw call still works in the coordinate space it was written for. --board-max is the ceiling on how far it stretches: 1100px windowed, 1500px fullscreen.
Everything on the game canvas is drawn per frame from primitives. No sprites on disk, no shader files, no asset folder.
- Bloom — the scene is downsampled through a chain of halved buffers and composited back additively. The downsample is the blur.
- Glow sprites — one radial-gradient sprite is baked per colour and blitted additively. Particles, the snake halo, food halos and the ambient starfield all come from the same cache.
- Gravity wells — a black hole pickup leaves a singularity that pulls every particle on inverse-square attraction until it collapses.
- The swallow — eating sends a wave from the head to the tail, swelling each segment as it passes.
- Chromatic aberration — opposed red/cyan drop-shadows on the whole rig, spiked by nukes, singularities, Fever and death.
- Warp streaks — radial speed lines during Fever.
- Screen shake, zoom, roll, strobe and CRT scanlines — camera and overlay work, all frame-rate independent.
LOW GFX turns off every one of these. The game plays identically; it just stops painting.
No design doc. No sprint board. No tickets. No stand-up. No architecture review. No "let's circle back on the particle budget."
I sat down, put the throttle on the floor and never lifted off it. The synth engine, the bloom chain, the gravity wells, the 43-trophy tracker, the gamepad rumble curves, all of it got built in one continuous full-gas run on vibes alone. When something felt like it should exist, it went in. When it felt slow, it got faster. That was the entire process.
The whole thing is still one file. That was never the plan, it just never stopped being true.
Vibes: kept. Brakes: never fitted. Gas: full.
This game strobes hard by default. Full gas has an off switch, and here it is.
The GFX button in the HUD switches between ULTRA and LOW; LOW drops the bloom, the screen shake, the full-screen flashes, the chromatic aberration, the warp grid, the ambient particle field and every looping strobe animation, and the choice is remembered in localStorage.
If your OS is set to reduce motion, the game starts in LOW automatically and the flashing elements stay disabled even if you switch back to ULTRA.
| 🔥 ULTRA | 🧊 LOW |

Same snake, same board, same 31x combo. Only the painting changes.
No npm install. No docker run. No bundler. No config file. No build steps. There is nothing to install because there is nothing to install.
