Pilot your submersible down into the sea cave. Your headlamp is the only light below 90 m. Catch glowing creatures before the air runs out.

CATCH

Comb jelly · 1 glow

Lanternfish · 3 · darts away from your lamp

Ghost ray · 10 · below 330 m

Abyssal queen · 50 · on the cave floor

AIR

Drains faster the deeper you go. Silver bubble vents refill 30%. Hitting rock costs air.
