What's New in The Long Descent

1.3.2

September 25, 2026

A quieter screen, and rewards that wait their turn. THE REWARD OFFERS MOVED OFF THE MAIN SCREEN — Three optional video-reward buttons used to sit permanently under the objective bar. They now live behind a single Free rewards button, which opens a list of what is available. That button never starts a video on its own, so you can no longer land in one you did not choose. A GAP BETWEEN VIDEOS — There is now a minute between optional reward videos, and anything that has to wait tells you how long instead of doing nothing. Nothing you can earn has changed. The daily amounts are exactly what they were; only how often and how prominently they are offered is different. If you own Remove Ads, none of this applies to you — your rewards are still one-tap claims with no video and no waiting. SIX SEASON HULLS LOOK LIKE HULLS AGAIN — In the store they were falling back to a placeholder symbol instead of the vessel. THE REWARD TIMER COUNTS DOWN — It used to freeze on whatever second you opened the list at. OPTIONAL REMINDERS — If you said no to reminders when the game first asked, it may ask once more after a week. Once. You can always change it in the menu.

Response from developer

sorry you feel that way :( i personally rarely to never watch the ads and genuinely don’t feel inhibited by the ads being there or affecting my gameplay. thank you for downloading and trying my game!

Good but lacking difficulty or friction

I like the game, but it’s way too easy. I never had to reinforce (the prestige system) even a single time.

Response from developer

noted, i appreciate the honest feedback! i too was able to get pretty far before my first refit (iirc about e6 cores the first time) but eventually prestiging definitely did become necessary for me. i did design the game to get more challenging the further you go. i’m interested to know deep you can get with never reinforcing! feel free to reach out through the privacy policy > contact email.

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.

Response from developer

fire thank you i’m glad you’re enjoying it. keep diving!

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!
