What's New in The Long Descent

1.3.4

October 13, 2026

Your Bestiary keeps your best catch. Selling a rare fish could quietly lower that species' record to a lesser edition you still held. It never does now — the record only goes up — and selling your last copy of your best edition asks first. Hull upgrades you can see. Every reinforce now lands on the hull itself, and each new hull mark gets its own reveal. Pearls, explained. Tap the Pearl counter any time to see what Pearls are, where they come from and what they buy. The Salt Choir and Black Bloom season hulls are now fully painted. Also fixes how anonymous play data is reported on iPhone and iPad, for players who opted in.

Great incremental

Love the game. Well designed. The dive mini game is fun and has a challenge to it. Spooky and creative fish.
BUT.
On spending pearls, and possibly real money, please ask, ‘do I want to’. Especially the dice roll on the fish rarity. Allow people to disable the pop-up maybe, but you’ve got ‘make pearls’ and ‘spend pearls’ looking exactly the same.

Great

Tossed some coin to the Witcher. Needs more. I’m just quantesizing to the same stuff again and again. Looking forward to the development

Interesting and Unique!!

I LOOOOVE THIS GAME, It’s a very unique idle game and I find myself actively paying attention to the lore. Sometimes when tapping I click past the zone descriptions and those are the COOLEST parts!! So be sure to take your time! I know there’s an index for all the fish and a captains log for the words but I would love an index for the zone pictures the art is amazing

Bad Design

It was fun at first, but who thought it was a good idea to provide a tiny part of the screen to tap, and then an option to use your premium currency to go down one level right next to it? Just one tiny off tap made me lose all the pearls I slowly earned, it’s stupid, a waste of time and I’m done with it.
