🎯 OBJECTIVE

You pilot a bioluminescent hydrofoil sled in first person down the Trench Conduit — a current-carved crystal chute that plunges from a sunlit coral shelf into the crushing hadal black.

Clear all 120 descents, chain combos, thread the VORTEX GATES and survive the TRENCH SURGE — the last 20% where the current screams and every point is ×3.

You carry 5 O₂ cells (lives). Every impact burns one.

🔥 COMBO & LUMEN

• Every pickup grows your COMBO: +0.2 per 4 items, up to ×10.
• Any impact resets the combo — keep the dive clean.
• NEAR MISS — shaving past a hazard pays +800 and grows the combo.
• Speed itself generates Lumen. The faster you fall, the richer you get.
• TRENCH SURGE (last 20%): huge speed kick + ×3 on everything.
• Descent end: Distance, Perfect-Gate, Near-Miss, O₂, Time & Flawless bonuses.

⚠️ HAZARDS — DARK HULLS WITH A RED GLOW

• 🐟 BARRACUDA — hunt in weaving patrol lines, lead your line
• 🌀 WRECK PROPS — spinning propeller bars, time your pass
• 🎐 JELLY CURTAINS — sting-fields that pulse on and off; slip through while dark
• 🚧 WRECK GATES — collapsed hull plating that always leaves exactly one gap

🤿 DIVE HELMS & 🏆 RANKING

Five full-face dive helms are available for every descent, each with a different blessing — Lumen, top speed, shield duration, sonar-pull range or combo growth. Your chosen helm is drawn over the whole screen with its own sonar sweep and bubble stream.

WORLD RANKING — TOP 100. Type your name after any descent or wipeout to claim your place on the global leaderboard.
