Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,402 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About

On the outskirts of a small village stands a massive tree whose canopy disappears far above the clouds. While grandiose on the outside, its interior houses the humble Mortem Post, which receives and delivers letters from those who have passed on. Deciding to break protocol to lend a helping wing, Rain, a flighty little courier takes a skittish girl by the name of Mila on an adventure through the inner workings of the post office. Together, they search for a letter containing the last words of someone who seemingly never existed.

One part visual novel, one part puzzle adventure! Follow Rain and Mila through the mysterious Mortem Post as they meet with various couriers working throughout the tree and make use of Rain's trusty stamp collection to overcome a myriad of obstacles that stand in their way!
Often during your adventure, you'll need to take advantage of stamps to tie words together in intuitive ways to help Rain and Mila out of various sticky situations. No two puzzles are exactly the same -- from choose-your-own-adventure style outcomes to stealth missions, you'll see just how versatile Rain's stamps can really be!


cv: Beth Pierce
A rookie courier at Mortem Post and granddaughter to the postmaster. As a no-stamp rank, she's still learning the basics, such as handling front desk duties or sorting ground-level mail.
While she loves her job, she's prone to bending the rules that come with it, often causing trouble for herself when her mentor inevitably finds out.

cv: Mel Valentine
A young seaborn girl from the village of Vitae. She's been a regular at Mortem Post recently, coming in every day for the past three weeks asking for a letter she's expecting from her dearest friend who has recently passed on.
A bit of a crybaby, her tears upon hearing that her letter still has yet to arrive are what move Rain to take her on an adventure through the back of the post office.

cv: William Maloy
Though a courier by name, in actuality Mizore's duties to the post mostly involve the upkeep of the tree's exterior. Trimming branches, ensuring it's continued health and so on. While the tree stretches upwards forever, they never stray higher than the clouds, lest the task become impossible. They have a friendly, laid-back demeanor, finding much amusement in Rain's day-to-day ordeals. Arguably too much, as they end up playing along with just about anything she readies as an excuse and, as a result, lets her get away with pretty much everything.

cv: Elissa Park
A Three-Stamp ranked courier and Rain's Big Sis (no relation.) Unlike her fellow galekind, Neve is firmly planted to the ground thanks to her missing wing. She's found a comfortable position in the post office that takes advantage of this. Staying out of the sky allows her to get to know the other villagers in a way those who stay airborne do not, and as such, she's able to deliver letters that arrive at the post office with vague recipients such as "the kind regular who always visited my shop" or "the woman who delivered flowers on my birthday."

cv: Vyn Vox
A courier who has achieved the rank of Five-Stamp. With her prestige comes no small amount of additional responsibilities, including the training of new staff. Her newest trainee, Rain, has caused Caile nigh endless grief. The young galekind's reckless disregard for the rules of the post clashes constantly with Caile's ceaseless chase for perfection. Rain's repeated patterns of defiance have only doubled Caile's efforts, however, and it's not uncommon for her to hover around Rain for much of the day if her duties do not pull her elsewhere.

Mi nuevo juego favorito QwQ
Such an adorable game
小品级小甜点。没有雷点也没特别值得强烈推荐的地方,硬要说的话是"两个小女孩互相信任的羁绊可以跨越各种困难?"。像作者为oc做出来的游戏,彩蛋里的背景和人物设定非常详细。讲的是小邮递员陪小女孩找一封未收到的信件的故事。感兴趣可玩。
小雨找帽子那个成就都有什么啊。。。找到 6/7 实在找不到了,还差个给米拉的礼物。好麻烦的成就。
A heartwarming game with a story that had me audibly gasping alongside an irresistibly beautiful art style, all under two hours (including extra content). Just a wonderful time that will put a smile on your face. This game deserves far more love and attention.
Cute, short, well worth it.
