What's New in The Long Descent

1.2.1

September 10, 2026

Two things a player asked for, and three fixes. AUTO-HARVEST BUYS THE BEST MODULE IT CAN AFFORD — It used to pick whichever was cheapest, so however deep you got it kept buying the shallowest machinery instead of advancing your rig. It now always reaches for the strongest module your energy will cover. SALVAGE ALL — One button strips every outgrown module at once instead of tapping through the list. It tells you what it will cost from your salvage allowance before it runs, and stops exactly where stripping them one at a time would. THE FLOODLAMP NO LONGER SHOWS A PRICE IT CANNOT CHARGE — While the lamp is fully lit for your depth, the card now says so instead of quoting an energy cost that could never be paid. THE DEPTH IN THE HEADER MATCHES THE BAR BESIDE IT — Generated zones remembered the number format you were using the first time you arrived, so at extreme depths the header and the depth bar could disagree about the same number. The header is also cleaner now: it names the zone, and leaves the depth to the mini-map. YOUR FIRST MODULES CAN FINALLY BE SALVAGED — Collector Drone, Pressure Turbine, Salvage Claw and Thermal Vent Tap paid out so little that the game rounded them to nothing, so those four rows never collapsed no matter how far past them you had built. Good luck down there.

I LOVE IT

Im just starting is but the logs and the new depths are so GOOOD i bet it will be fantastic later on.

Fun and charming little game

Fun little game to pass the time the only things that I think could use improvement is the auto harvest upgrade actually getting the best module you can buy instead of whichever one has the lowest number for example the angler lure having 10 while the drowned array had 20 it would choose the first until it had surpassed the module that is much further down the line. The other thing is a button that would allow you to salvage all modules that are available to be salvaged instead of having to go through the list and salvage them one by one. Other than those two things it’s been fun.

Response from developer

Thank you for the review. You caught something I totally thought was fixed, and suggested something that I never even thought of. The newest version, live now, 1.2.1 implements both of these changes. Keep diving!

Poor instagram

I really like this game I needed something to occupy me, a non pushy, aesthetic, self paced idle game like this is perfect if love if you continued your work and this game looking for more from you and others like you

Response from developer

Thank you so much. This is my first game, so any and all feedback is appreciated. Super happy to hear you are enjoying it and dont you worry, there will be more games coming soon.

A fantastic idle game

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!!

Response from developer

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

Easy progression without getting board. No forced ads. Unable to copy and paste code between devices. Game Center sync feature would be nice.

Response from developer

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.
