    HOW TO PLAY

    🖱️
    Steer. Your serpent always follows the pointer (or your finger). It never stops moving — plan turns early; big serpents turn slower. You spawn as a ghost for 3 seconds — untouchable and harmless — so get your bearings before the arena gets real.
    ⚡
    Boost. Hold click / Space / the ⚡ button for ~1.8× speed. It burns your length and drops orbs behind you — a trade, not a freebie. You can't boost when tiny.
    🔮
    Eat. Orbs are pulled magnetically toward your mouth; bigger orbs are worth more. Your score counts everything you eat and never stops climbing — body length maxes out at Leviathan bulk, but the score has no ceiling.
    ⚔️
    Fight. A rival only dies when its head hits your body — bodies crossing is harmless. Boost across a rival's path so its head runs into your side. When one is about to crash into you, a pulsing red ring marks its head — that's your kill. Head-on? The longer serpent wins — ram small ones, dodge big ones.
    🎁
    Power-ups. Grab the glowing rings: ⚡ free boost for 6s · 🧲 huge orb pull for 10s · 🛡️ survive one death · 💠 instant +20 length · 🦎 rare chameleon (re-colors you against the crowd) · 👿 rare Soul Swap — steal the size of the biggest snake near you (your score stays yours; get close to a giant and take its body!). Bots want them all too.
    🧬
    Evolve. At length 40 / 110 / 210 / 340 you change form — bigger, faster, and visibly scarier. A crowned serpent with fins earned it.
    👹
    Bosses. Every couple of minutes a 3-HP boss serpent invades and hunts you. Bait it into crashing into your body three times — victory pays mass and a rare skin.
    👻
    The Phantom. Sometimes a ghost serpent haunts the arena for ~25s. It can't be killed and bodies pass through it — but its touch drains your length. Keep your distance until it fades.
    🧱
    The wall. The red ring is electrified and kills instantly (only a 🛡️ shield saves you). Never let a fight push you into it.
    🔥
    Combos. Eat, catch prey and kill rivals in quick succession to build a combo and a rising score multiplier (up to ×5). Keep feeding to keep it alive — it lapses after a couple of seconds. Go ON FIRE for the big scores.
    📈
    Levels. Every point you score in any run becomes permanent XP — levels are endless and titles grow with you, from Hatchling to Cosmic Leviathan. No run is ever wasted.
    🎯
    Challenges. The 🎯 menu button lists 12 one-run goals — reach a length, score a milestone, slay bosses, survive minutes. Complete 6 to earn the Vanguard skin and all 12 for Champion 👑. They give the late game a target beyond just surviving longer.
    🎛️
    Make it yours. Pick your Arena intensity (Chill / Classic / Chaos) on the menu. Pause anytime with P, Esc or ⏸ — the game also auto-pauses if you switch tabs. M mutes sound, FX: Lite speeds up older phones, and 👁 Ghost Mode lets you study the arena without risking your scales. After you die you can also Watch Arena — spectate the same live world, then Jump In whenever you're ready.
    🐀
    Prey. Live critters — rats, frogs, rabbits, lizards and more — scurry into the arena and run from you. Chase one down and catch it for a score & length bonus (bigger, faster ones pay more, and a rare 🌟 golden rat is a jackpot). Boost to close the gap — they sprint but tire, so stay on their tail. They ping the minimap, so hunt them like a real python.
    🐍
    The Nagin. Once in a while a mystical Nagin serpent glides through the arena to a hypnotic flute, trailing golden orbs. She's harmless — touch her for the Nagin's blessing (fortune & overdrive) and earn the Naga skin.
    ⟡
    Rare finds. Watch for the pale ⟡ crystal that drifts through the arena — chase it, it's worth more than it looks. And there may be a secret or two for the curious…
    🏆
    Win. Camp crash sites for orb feasts, encircle smaller serpents to trap them, and check the minimap so a Leviathan never surprises you.

    ABOUT THIS GAME

    Neon Serpent Arena is an original game inspired by snake.io and slither.io. The genre DNA — grow by eating, boost burns mass, head-vs-body kills — comes from those classics. Everything else was rebuilt from scratch in vanilla HTML, CSS and JavaScript.

    What's different here
    • Honest AI — named bots with readable logic, not fake "multiplayer" pretending to be humans.
    • Circular arena with a lethal electrified wall — no safe edges to hide along.
    • Deterministic duels — head-on crashes are won by size, not reaction-time luck.
    • Evolution — 5 forms that change your size, speed and look as you grow.
    • Combo & multiplier — chain eats, catches and kills for a ×1→×5 score multiplier and go ON FIRE; every second counts.
    • Contested power-ups — overdrive, magnet, shield, feast, plus rare 🦎 chameleon & 👿 soul-swap, hunted by bots too.
    • Threats & events — green-anaconda bosses you bait to slay (tougher the higher you climb), and a phantom you can only flee.
    • Running prey — 🐀 rats, 🐸 frogs, 🐇 rabbits and more scurry in and flee; chase them down for a bonus.
    • Mythic surprises — a rare 🐍 Nagin glides through to a synthesized been melody and blesses you; skins drawn from snake folklore (Naga, Rainbow Serpent) — original, no licensed brands.
    • Hidden depth — Cosmic Shards, secret skins and a code or two for the curious.
    • Goals to chase — a 12-step Challenges ladder and daily challenges, with reward skins for the dedicated.
    • 🏆 Rank ladder — climb Bronze → Master (three divisions each) on your best run; a rank badge on the menu and a RANK UP! moment on the death screen. Skill only, no pay-to-win.
    • Endless progression — lifetime XP with uncapped levels; every run counts forever.
    • Player-first controls — pause, four arena intensities (incl. a gentle Kid Mode), sound & FX toggles.
    • Static & private — no game servers, no ads, no accounts, no downloads; just privacy-friendly, cookieless, anonymous visit counts (Vercel) so we know people are playing. Your scores stay on your device.
