The ocean went silent. You're being sent down to find out why. The Long Descent is an idle deep-sea odyssey: pilot the last exploration probe, harvest energy from the dark, and descend through 31 hand-written zones — from the sunlit shallows to places the sea itself doesn't talk about, and past them into a deep with no floor. DESCEND — Every zone multiplies your output and deepens the story. Your pressure hull must be re-certified at each boundary: reinforce the ship, watch it visibly armor up, and push past the wall. DISCOVER — Catalogue 93 painted deep-sea species, each with its own lore and passive bonus. Rare editions (Shiny → Abyssal) make every sighting a roll of the dice. DIVE — A skippable reflex minigame: steer by headlamp through painted mines and jellyfish for an energy burst. The deeper you go, the dimmer your light. REFIT — Surface, trade your depth for Cores, and descend again — permanently stronger. ◆ Fully painted world: ship, creatures, machines, story vistas ◆ Offline progress — your drones keep working while you're away ◆ Plays in minutes-a-day sips or long hauls; no energy timers on gameplay ◆ No forced ads, ever — every ad is a button you choose to press, and it pays you for pressing it ◆ No account, no server — your save lives on your device ◆ Analytics are opt-in, anonymous, and off until you say otherwise ◆ Optional Pearl bundles support development — the weekly featured bundle carries real bonus Pearls, and there are no fake sales here The road on the seabed is paved, straight, and older than the coastlines above. Who built a road down here? Descend and find out.
