The ocean went silent. You're the probe they sent to find out why. Harvest the dark, certify your hull, and keep descending — the deep no longer has a floor.
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.
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.

◆ 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

◆ 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.
Only positive things to say here. It’s a fun game and it looks and plays great. The IAP’s are fair if you want them but not needed at all to enjoy the game. I would highly recommend giving this one a try!!
Developer Response
Thank you for this — reviews like yours are why a small game keeps getting updates. There's a lot more deep on the way.
Easy Progression
Mandracore
Easy progression without getting board. No forced ads. Unable to copy and paste code between devices. Game Center sync feature would be nice.
Developer Response
Thank you — this review changed the game. You were right: save codes couldn't really move between devices, and 1.2 fixes it properly. Codes are now 88% smaller and importing on a new device actually works. Cross-device sync is built and coming in the next update — your save will follow you through iCloud, no codes needed.
THE DEEP IS ENDLESS
The wall is gone. Past the old floor the machinery keeps coming — new modules forever, new echoes, new trophies — down to a real ending more than six times further out. Production, energy and every price keep going as far as you can push.
THE DEEP PUSHES BACK
Every zone now costs more of your income than the one before it. Forever — no plateau, no depth where the descent stops asking anything of you. Reinforcing your hull prices in the strength you bring: your first vestige levels are free, then the water charges a growing share of everything you have built. Descending itself stays cheap. The frontier is what you earn.
VESTIGES — A SECOND REFIT LAYER
Push your frontier deeper and every Core you own is worth more, permanently. Unlocks on your fifth refit.
DIVE RUNS FLY FREE
The probe is off its rail — drag anywhere and it goes there. Half the motes wink out partway up, so depth is a real decision, and the hazards aim at where you are. Plus a whole dive bench in the refit shop: longer dives, a wider pool, a third life, and a lure that brings the deep to you.
YOUR BESTIARY PAYS FIVE WAYS
Descend cost, tap power, Cores, dive hauls and offline time — not just production. Echoes inherit what they echo, so the endless half of the collection is as varied as the authored half.
YOUR SAVE MOVES WITH YOU
Save codes are 88% smaller, and importing on a new device finally works.
ALSO
• Reinforcing the hull costs 40% less, so early walls are a pause and not a stop
• Modules you have outgrown can be salvaged for Cores, each worth what it was worth when you built it
• Energy chests surface while you play
• Manual Harvest rebalanced end to end — tapping is worth doing everywhere, and is no longer the only thing that works
• The trophy shelf never empties
• Landmarks all the way down: Sirius, the Orion Nebula, the heart of the galaxy, the edge of the observable universe
• Smoother on deep saves
