From the cave
What you're diving into
- Procedural caves. Every run builds a fresh ~400 m flooded tunnel from a seed — bends, narrows, spike fields, no two routes alike.
- Sonar, not floodlights. The deep dark hides everything; your sonar ping (4 s cooldown) is what reveals glow cores and the way ahead.
- Oxygen economics. Air burns faster below 120 m and boost guzzles it. Scoop glow cores for +120 each — deep detours only pay off if your line is clean; leftover air converts to score at the gate.
- Hull matters. Rock spikes, jelly impacts, and fresh wall impacts strip hull; at zero you are a very expensive paperweight.
- One clean win condition. All 8 cores in, then fly through the exit gate. Oxygen left over converts to score.
