One tide. Twenty minutes.
The whole coast runs on one clock, the same for every diver.
Get out in time, or your pack sinks where you fell.
What's in the box
- The tide
- The water falls for ten minutes and rises for ten. Shallow caves stay open most of the cycle; the deep ones give up their floors for just a few minutes. Every fourth tide is a spring tide, and the Maw opens for about ninety seconds.
- Seven sea caves
- From the shallows to the Maw. Caves are dark, your lantern is how far you see, and the map fills in only where you've been. Passages loop, sags flood early, and currents pull at you in the deep water.
- Three skills
- Scavenge tide pools, mine veins, and pick sea chests. Each is a short game you play with one tap.
- Drown and lose the pack
- Miss your last way out and your pack sinks in a wreck where you fell, for anyone to loot. Your gold in the bank is always safe.
- Parties of four
- One coast shared with everyone online. Dive together in parties of up to four.
- No account to start
- Name a diver and you're standing in the square. Nothing to install, and it plays on desktop or phone.
