A downloadable game for Windows, macOS, and Linux

Far north on a small island group, a tragedy has happened. Breaking the Postal Secret is the only way to unravel the mystery of the dead postman.

Undercover as the new postman, it is your job to find out what happened by getting to know the islanders and their stories. Even though you may start to like them, reading their letters and manipulating their relationships is the only way to unravel the mystery. The Postal Secrect no longer counts!

I liked this game, but after the very first clue I never got another one! Even when everyone was at full relationships except for Ole (who didn't have any letters until spring). 

Therefore I couldn't get very far :(

Update: Nevermind, I understand now that the relationships much match the yellow envelope! I must have missed that last time, I'm getting plenty of clues now

Hey, nice that you were dedicated enough to spot it yourself :) We got notified several times that this information is not clear enough communicated... Who knows if I have some free time I might do something about it^^

Anyways hope you still had a good experience even though this happened? :)


This is a really fun game, and concept. I had so much fun with it that I decided to include it in my series of Itch.io reveiws! Really great work to everyone involved, I'll be looking forward to seeing what you all do next!


We feel honored! Awesome to hear you had fun playing it :) Also thanks for your feedback and critique. We will share information here on itch as soon as we have something new coming up!

Have a nice day


Love the Art style, The story was really well layed out. Really Enjoyed it..

Best regqrds,

I can't start the game. The story never starts. When I open the game, it puts me in the game without music or sounds. There's nothing I can do other than click on islands and click out of them. I tried un- and reinstalling the game, but it didn't work. Clicking "New game" or "Load game" don't work either. Can I fix this?

Hi, thanks for letting us know! If you don't mind you could send us an email to ymargames@gmail.com with more details (Windows, Mac or Linux which version do you have and do you play in 1080p?) so we can see what we can do :)


An interesting game. Had fun testing it. Loved the design and the story.

Nice to hear, thank you for playing and sharing! :)

hey, I´m trying to play the game but I´ts not working, everytime I start the game the letter appers and nothing else happens, like the game doesn´t really starts, can you help me?

Oh, alright! We can try:) We Never had that kind of issue before but if you can give us some more information maybe via email, we can see what we can do. Other than that try to click "New Game" or "Load Game" in the Main Menu after reopening the game or delete and reinstall it. Maybe this solves the problem.

Hope that helps!



This was a very cool game with cool mechanics ! Maybe my english is too bad, i got 0/4 but i enjoyed the stories and the characters !

Good job !

That's nice to hear, thank you very much! :) Unfortunately, we can't translate it... Glad you still had fun and hopefully you could find all the clues in the end? So you at least know what happened.

Thanks for the feedback and have a nice day.

Yeah i got all the clues in Autumn, but i didnt manage how to organize all my thought and i was mostly guessing what happened.

When i discovered the whole story i was "damn, that was that deep and complexe" and i think i wouldn't have the correct solution even if i spent more time :D

But this was a good game, i enjoyed my experience nevertheless :)


Hey Dev.

I uploaded my play through today... and well... well i guess you will need to watch to see how i did... it was a real roller coaster i'll tell you that much.

Thanks for sharing, we definitely will check it out! :)

Great visuals and a sneaky story that does need a lot of clues in order to find the truth. :)


Thank you very much for playing, sharing and the feedback! You were pretty good at solving the mystery, well done. :)


Hehe, I drew from my point-and-click experience to get to the bottom of the case. Looking forward to your future projects! :)


I saw your game on Nookrium's live stream, really good looking. Love the 'Clue' like feeling it had to the game. I'm guessing that there is only one story but if it's randomized each time that would be epic. Great work guys.  =]

Thanks for stopping by! Glad you liked it :) So far there is only one riddle to solve but the letters are randomized. Maybe there will be more stories in the future.

Did you see his playthrough? It was awesome to see him playing and figuring out the solution.


Hey Dev! I included your game on this week's Indie Game Playlist!

Thanks for showcasing our game. Such a nice video format :) We are looking forward to your playthrough and upcoming videos!


Love this game. super fun to play and try to solve the mystery. It reminds me a little of the board game Clue. I loved the credits with the full story at the end as well. If you choose to develop further it would be cool to have new levels with a different mystery to solve.

Thank you for your feedback! Additional mysteries are in fact something we have thought about for the future. :)
