Fixes we are working on:
We are investigating issues on the Steam Deck since the new Steam OS update.

Ensure the Proton Compatibility 9.0-4 setting is turned on for best results on the Steam Deck.
We are experiencing a bug with Unity where the game sometimes stops players from being able to interact with items after clicking many times. We are continuing to put fixes and safeguards in place, but you may still find some edge cases. Please feel free to continue reporting this, with any details you have about what happened directly before the clicking issue started.

We've been so excited to see all the new employees here at the post office, and we want to thank you all for your diligent work and deep curiosity. We've welcomed over 3,000 postal workers, we've watched people find the super secret ending, Shelly has been out living her best life, and thousands of pieces of mail have made their way to the right people. You've also illegally opened mail, met a Stranger who can absolutely be trusted, met a few interdimensional entities, and taken some time in the penance chamber. Hey, it happens.
We also want to thank you for helping us identify bugs that you've encountered so that we can correct them and get the post office working at peak postal efficiency. We're working around the clock here at FlatNine Games to continue squashing those bugs and plan our next content update, so keep an eye out throughout the coming weeks and months!
If you need a clue on a puzzle or want to report a bug and want the fastest response, we recommend checking out our Discord, where fans can help you solve tough puzzles, give you hints, share theories, and devs can help with bugs you may encounter. We are also active in Steam discussions and via email, but Discord is the quickest way to get an answer!
And finally, if you want to help more people learn about the joys of the post office, please consider leaving a review! The value of a review cannot be understated on Steam, and we would be so grateful to hear from you.
Thank you, dear postal worker, and we'll see you soon, Rookie!

Remove spiders from horrific packages.
Relocated a certain missing child to allow you to find again. (Note: one reason for the disappearance was that the storyline was incorrectly triggering as "completed" so we're looking into how to correct this so that you don't miss out on the story if that happened to you! We'll update when we roll that out.)
Standardized the size of letters and outlawed tiny letters once again.
Corrected an issue where Sedna's gift made her forgetful as well.
Ensured the drawers of the letter desk function correctly. (This is to address some difficulties in completing the note puzzles at the letter desk.)

Fixed story items having issues for players who found a series of three notes and received a certain gift.

Reminded Amon to show up to help train you after your first week if asked.
The shredder now remembers the taste of packages and will identify them correctly when you are asked to shred them.
Unless there's an emergency, we're going to avoid patching for a few days while we gather more bugs and put together a larger more robust patch of more fixes. As always, please continue to report any issues you may be having, and we'll add them to our list!
Happy mailing, friends
We are closing the Kharnym Isle sewers over the weekend. It seems that mail wrinkles involving \Bitter End\ and \wet letters\ are causing some issues with mail processing, and so we're de-activating those wrinkles until the start of next week when we come back to work! Mail affected by these wrinkles were all being registered as Incorrect.
Fixing a softlock when pressing "Escape" instead of "E" while staring at the \Starry painting in the bedroom\. As we all know: there is no escape. Now there is only "E"
Our programmer will be taking part in his mandatory relaxation period over the weekend, but please continue to report any issues you have and we'll hit the ground running on Monday, working to address as many issues as we can.
Thank you!

We hope this job lives up to all of your hopes and dreams!

Welcome to the Kharnym Isle Post. Your forever job awaits you.
Happy mailing!
~FlatNine Games
As we approach the 27th, we've made the decision to delay release of Letter Lost. We chose to delay in order to do further playtesting to make sure you don't escape before your time keep the mail running smoothly. We're a very small team, and we're working around the clock to get the game to its peak postal potential so you can be ready to start your shift.
We will be announcing the official new release date during the Summer Games Fest Women-Led Games Showcase on June 4th, but rest assured, the release date is not months in the future, it is weeks.
We know you're so excited to get into the post office, and we're so grateful for all of your support!
In the meantime, here's a list of fun very out of context tidbits/spoilers to intrigue you:
As far as we're aware, there's still a secret left undiscovered in the demo that nobody has found. It will still be present in the main game.
Liv is not the only voiced character, but some playthroughs may not discover this. (Excluding radio voices)
It is possible to unlock another picture to appear as Employee of the Week.
In his original design, Albert was married to Lilian and only ever appeared with her. He was cut from this storyline to be used elsewhere and accidentally became much more interesting.
The radio has a few fun hidden secrets that we don't think will be discovered for quite a while.
Because of a bug, only one playtester found a means of "escaping" the post office. She has been sent to the Penance Chamber and remembers nothing of the ordeal.
There are items and actions you have access to immediately upon starting the game that are directly involved in some endings. But what are they??
"Underworld Resources: It's like Human Resources but for the Underworld."
The demo had 4 stories you could discover while playing. The full game will have closer to 20, most with multiple endings to experiment with.
There is a phone number that gives different results depending on when in the game you call it.
You are not the only person on the island who Indric has spoken to.
There is a segment of the radio voiced by fan-submitted voices of (totally normal) spooky/ghostly lines.
There is a recording you can find of a dance tutorial that is involved in a puzzle.
It is possible to die of old age in the full game.
We'll see you at the post office soon!
-Liv
You've waited patiently, you've checked the mail every day, and the end of the wait is near. The mail arrives in just one month, and we can't wait for you to jump into your forever job at the post office.
Wishlisting the game, telling your friends, checking out the demo, letting content creators know about the game, and joining our Discord are all amazing ways to help us as we lead up to launch! Once the game releases, all of those PLUS reviewing the game! We want to get the word out to as many people as possible about this once in a lifetime job opportunity, and reviews help us imprison hire as many new recruits as we can.
Our ARG is full of puzzles, choices, secrets, and two of the three phases are live NOW! The final phase comes out soon enough, so get started now to be all ready for the final drop.
Click here to begin our ARG journey!
Thank you for all your support, and we can't wait to welcome you to the mail room!
~The FlatNine Games Team
The countdown is on for launch, and so we wanted to share what we're working on each week leading up to our release! This week, we've got lots on the our plate, including collectibles, achievements, and some secrets....hm...
And with that, we're off to sort the mail!
-The Letter Lost Team
We had an absolute blast this week watching you all take on the new and improved Letter Lost demo over Next Fest! Thank you all for signing up for your forever jobs, and we know Kharnym Isle is grateful for all the new postal employees that have arrived.
If you're eager for more content before the game releases, the demo offers 4 storylines you can pursue, some with multiple endings that you can find, along with countless secrets, bits of lore, and easter eggs! Can you find them all?
And if that's not enough, check out our live ARG! Try your hand at the Aptitude Test, and dig into the historic Kharnym Isle website, which is totally normal and not weird at all!
Our Discord is also a great place to let us know what you thought about the demo, work with the community on our ARG, or share any bugs you may find. We are still very much in development, and would love to hear any feedback you may have!
Thank you again, postal warriors, for making Next Fest a smashing success. We can't wait to bring you the full game in just a few months!
Postal Warriors, it's here, the official Letter Lost trailer! Are you ready to mail your days away? Good, because this is the last job you'll ever have!
Letter Lost is a totally normal post office game, releasing in May 2026. And in the mean-time, be sure to check out our updated demo in celebration of Steam Next Fest, full of new secrets, new characters, an additional day to play, and much more!
Steam Next Fest is around the corner! A shiny new Letter Lost demo will be premiered during the festival, so be sure to check it out ahead of our full release in May. You will see new characters, an updated tutorial, new secrets, updated UI, controller support, one additional day, and a new item bar!
Happy mailing, post workers!
-The Letter Lost Team
As we approach Steam Next Fest and our launch in May, we've been working on updating the demo with some new features and fixes! Check out the list below to see more details about what's to come in the fresh new demo!
See you in the mail room, postal warriors!
-The Letter Lost Team
A bit of Letter Lost news for you today! If there’s one thing we know, it’s that the mail needs time. As a team, we’ve decided to shift our release from March 2026 to May 2026 to give us some more time to refine and polish the game before its full release. We know that it’s always disappointing to hear when an exciting package won’t arrive when anticipated, but we feel it’s the best thing for the game you’re all so excited to play. These extra two months will give us more time to polish the game, add more secrets and storylines, and dedicate more time to controller support and Steam Deck testing. So, hold onto your job applications for two more months, and keep an eye out for updates before then for some fun surprises and reveals.
-The Letter Lost Team
Greetings New Hire!
Your orientation packet has finally cleared processing, which means we can officially announce that the Letter Lost demo is now available on Steam!
We are so thankful to be able to make this announcement during the Choose Wisely Festival and stay tuned in a couple days for the Women Led Games Showcase where we will have another announcement planned!
After a few years of only being able to show this to a small group of people, we're beyond excited to move forward with the release of our demo. It means so much to see our fans eagerly await when they can start their full shift at our post office, so we want this demo to be a sneak peek at what's in store for them, and help us continue to shape the best possible forever job for them.
Kharnym Isle has been waiting a very long time for another postal worker. We are so excited to have you here at this perfectly ordinary workplace with perfectly ordinary responsibilities:
Stamp the mail.
Sort the mail.
Process the mail.
Management would like to stress that for your safety, stepping outside of the Kharnym Isle Post Office is not part of the protocol.
The demo is your first four days of work at the post office, intended to ease you into your new place of permanent employment. You’ll learn the basics of running the mailroom, have a few additional wrinkles thrown your way, and get to meet a few customers who may have more to their stories for you to discover. Upon full release, the game will continue past these first introductory work days, and introduce many more characters, secrets, and challenges to uncover.
These first four days should take somewhere around an hour to get through, but we would encourage you to restart when you're finished. Make different choices, explore different rooms, and you may just make a few discoveries along the way...
The residents of Kharnym have stories to share, some whispered, some written, some you wish you didn’t know about…
Please follow protocol and process the letters and packages as instructed.
Under no circumstances should you ever open or read the mail. Kharnym Isle Post will not be held responsible for any loss of life, sanity, or paycheck you incur for any unsanctioned mail opening.
Enough dilly dallying - it’s time to get to work! Our single-employee post office is complete with mandatory room and board. You’ll earn daily compensation you can use to improve your workspace. If you notice something strange, simply ignore it.
Thank you for joining us at the Kharnym Isle Post Office.
We hope your stay is productive.
We hope your stay is comfortable.
We hope your stay is…well.
We hope you stay…
Sincerely,
FlatNine Games
