About this game

AFTER MOVING TO THE BIG CITY
you got yourself an apartment, and secured a temp data entry job- just to keep you afloat till something better comes along. YOUR OFFICIAL TITLE IS A DATA CONVERSION OPERATOR, but you're really more like a warm body who types up all the junk computers still can't read.

D A Y - T O - D A Y
you go to work & process the images displayed on your terminal, and type up whatever random text is in front of you. Whatever can be made out, that is.
Sometimes the mail you receive is a little strange- letters and lost mail, some mangled and twisted, that have travelled from place to place with nowhere else to go.
Sometimes, it feels like it's talking to you directly through the screen...

USE YOUR KEYBOARD to type in various prompts, and attempt to decipher damaged images
MULTIPLE ENDINGS & buried secrets to uncover
NO TWO PLAYTHROUGHS are exactly the same (Estimated playtime: 120min per run)
A MASSIVE AMOUNT OF MAIL to voyeur through, and catch glimpses into other lives
ATMOSPHERIC HORROR MOOD with rich sound designed to crawl under your skin
Mouse & Keyboard are REQUIRED
Key re-binding is available, but a keyboard with Function Keys and Control Keys (Insert, Page Up/Page Down) is strongly recommended.
Featured in the HauntedPS1's Spectral Mall Demo Disc collection

DEAD LETTER DEPT. RELEASE - 1 YEAR ANNIVERSARY
It has been 1 year.I've decided to commemorate with a small bit of making-of reminiscing. As a project with the central theme revolving around a distinctly physical medium, it seemed pretty un-deniable that it would involve a lot of paper textures. In 2021, as a person whose entire career has more or less existed inside whirring boxes and glowing screens, I found myself a little bit artistically exhausted with the digital- craving any sort of excuse to bring in more physically sourced elements.So, as DEAD LETTER DEPT. development went on, I found myself increasingly now collecting envelopes in the mail that caught my eye, as well as collecting odd pieces of paper found on the ground. I wanted a varied range to source from. Anything now with a stain on it was suddenly incredibly valuable. The rare occasion that some mail got returned to me, was a precious gift. I wish now I had kept the mail that I burned (rather, what remained of it).Creating the mail was always a big mixture of physical + digital work. Mangling physical paper with writing on it, and then scanning it in was significantly faster and easier to get the right vibe (rather than trying to do it from scratch with digital), and it always seemed to give a better a natural look. It was also consistently a lot of fun to figure out many weird ways to beat up an envelope.Audio-wise, for a long while now I've made it a habit to always travel around with a portable audio recorder in my jacket whenever possible. Especially whenever I might end up say, in a random warehouse somewhere, with no one around, and a free moment to capture what something snapping or banging in it sounds like. It's a room tone to me that feels fixed somewhere between a church, a cave, and a tomb.After doing this for a long while I ended up with a collection of weird & unique sounds I loved, that also came from some key fond memories, but ultimately I never quite knew what to do with them. Until DEAD LETTER DEPT. finally gave me some opportu...Read full article on Community Announcements (Belief Engine)Patch NotesOfficial
Patch Minor Update 1.6.3
Welcome Data Conversion Operators, both junior and senior. Thank you for your hard work. This is just a quick minor patch.New in v1.6.2Quick fix for when Mouse Smoothing is set completely to OFF (previously the Yaxis apparently still received a smidge amount of dampening that would apparently cause light nausea to those sensitive to it)Update to fix Unity security bug for good measure. This was fairly low risk already thanks to the mitigation efforts of Steam, but it's still good to have killed it for good.Read full article on Community Announcements (Belief Engine)AnnouncementsOfficial

What better way to head into fall than by showing your friends you're into obscure typing psychological horror and possibly also reading their mail.Incidentally it's easy to expand it to other kinds of wearables, so if you're looking for something else in particular, feel free to let me know.GRAB THEM HEREDEAD LETTER DEPT.
