Black Dive: Rescue the Crew

Black Dive is a vertical horror cave diving game: lay air tanks in flooded limestone caves and an old coal mine, and bring trapped people out alive.
The story has 13 chapters, from Chapter 0 to Chapter 12. Act 1 (Chapters 0-4) is free to play. Acts 2 and 3 (Chapters 5-12) are an in-app purchase.
It plays offline. Only the leaderboards, Today's cave and purchases need a connection. Available in 12 languages, including English.

Three days ago Doyun and I went into the cave under the Black Well. At 133 bar I turned back. He never came up. Yesterday the rescue team called off the search.

AIR
Your main tank holds 200 bar. At 133 bar you've used a third, and the rest is for getting out. Set a tank in the cave, and on later dives swimming past it fills you back up.
Out of air, you can still hold your breath for 7 seconds. Reach a tank or the surface in that time and you live.

LINE
On new ground a yellow guideline goes down behind you. You move faster along it and can reel it in on the way out. Hit a wall hard and falling rock can cut it; old line wears through over the days. Kicked-up silt blinds you.
The wrist slate shows the way you came, your line, your tanks, the entrance and your depth.

HOLDING YOUR BREATH
Hold the button to use almost no air and hear which way the knocking comes from. Up to 8 seconds, then you gasp and lose air at once.

ON A DIVE
Below 30 m nitrogen narcosis sets in: the screen sways and a figure like a person stands at the edge of your beam. A moray eel bursting out of the rock makes you panic and burn air twice as fast. In the Blue Hole a big shark comes toward noise.

13 CHAPTERS
Three acts, from Chapter 0 "Three Days Before" to Chapter 12 "Crew 3's Room".
Act 1 (Chapters 0-4, free): Black Well, Tide Cave, Blue Hole, The Last Room. Find Doyun, the instructor Sujin, the photographer Taeo and Mr. Jung who mapped the caves.
Act 2 (Chapters 5-8): the flooded Deogam coal mine, where a collapse in March 1987 trapped seven miners.
Act 3 (Chapters 9-12): from the Side Well through the Whistling Neck to Crew 3's Room, 150 m down. Here you learn why the lines were cut so clean.
After Chapter 12 a deep zone opens below (included in the purchase).

CAMP AND CREW
Two dives a day. At camp you check the cave map, the tide, current, visibility and water temperature, which change every dive.
Everyone you bring out alive joins your crew: 151 people, each with an age, a job and stats such as lungs, calm and line work. Take up to 3 on a dive. Crew who run out of air stay down until you bring them out, then need 3 days sick and 2 recovering.

JOBS AND GEAR
Requests: rescue, body recovery, item retrieval, line checks, bringing back crew who passed out. No deadlines. One dive can finish several goals on the way.
Reward money buys tanks and upgrades your reel (70 to 114 m of line), torch and main tank (200 to 220 bar), plus tents, a cot and an infirmary for camp. The scooter from Chapter 3 runs 120 seconds.

MODES
Normal: die and you're back at camp before that dive. Tanks set and people rescued on that dive are lost; the line stays.
Hardcore: die and the world is deleted. Your record goes on the Hardcore board.
Today's cave: once a day, everyone dives the same cave with the same gear.
