The mission
Twelve resonance nodes lie scattered through the flooded rock canyons of the Kethral Trench. Your air is finite, the canyon is littered with spires and drifting contact mines, and the only way out is the ascent vent — which opens when every last node is logged.
Features
- Procedurally carved 3D canyon — terrain, ceiling and rocks generated from one seed
- Sonar scanning: fire a pulse to light up every node inside its reach
- Live hazard field: rock spires and slow-drifting contact mines gut your hull
- Oxygen race: each node you log buys air; every scan spends it
- Code-generated sound: sonar pings, collect chimes, hull alarms — no audio files
- Keyboard and touch controls, win and lose states, instant restart
How to play
Goal: collect all 12 resonance nodes, then dive into the green beam of the ascent vent. Win by surfacing; lose your air or your hull and the trench keeps you.
