“It's like Dave the Diver 3D with co-op and some really good art. You can even look to the sky on the roof.” — Steam review, 14 👍
Steam →Official store description:
"A casual 1-5 player co-op adventure where you explore the ocean, catch fresh fish, prepare sushi, serve customers, and grow your restaurant while uncovering the secrets of the mysterious Deep Blue."
Mornings you dive: shallows first, then the reef drop-off, then — once your oxygen gear and nerves allow — the trench. Evenings you run the sushi bar on the pier: slice what you caught, roll it, serve it before patience runs out. 1-5 players, split roles or chaos your way through. Early Access ($7.83) since August 20, 2026 by PaperPixel Games; the trench has story in it, and the community is still mapping it.
"We bought this to cook sushi. We stayed for the trench." — Steam review
At 60m in the trench there is a closed iron door with light behind it. Eight days, nobody has opened it — lanterns brought, full crews, 3am visits, saluting at it. Placeholder theory (EA unfinished) vs key theory (a key exists that we have not found). The devs replied on Discord with a single eyes emoji.
Frame lab + dive crew re-measured: oxygen burns on depth×time, with 40m costing 2.4x per second vs 10m (not the intuitive 4x — buoyancy compensation refunds some). Ascending steadily saves 18% vs sprinting up. Table is on the Beginner Guide; the sprint-ascent camp is officially dead.
One player staked out seven storm nights and claims rare fish spawn "within 90s after lightning" (11 samples, 9 hits). Dissent: n=11 is nothing, and you cannot watch every depth band. The community now waits for one big storm to verify together.
The day loop, oxygen ledger, first five fish, role basics.
Every species by depth: bait, time windows, rarity, storm-only.
Prep timings, rice temperature, menu unlocks, wasabi feud.
Margins, upgrade order, the patience math.
Role splits, unwritten law, dive signals, relay records.
The iron door, sunken izakaya, radio logs, three theories.
