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 2,400 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.

Reviews
I bounced off this VN the first time I started reading, but I went back a few days ago and gave it another chance. I'm glad I did. Once I got into the story, I found it pretty charming, and I like the incorporation of interactive elements in the form of the stamp system. They're closer to optional dialogue than puzzles, but they add an appreciated bit of extra immersion in the absence of a branching dialogue system. Upwards, Rain is short as far as visual novels go, but I think it's priced appropriately.
beautiful art and lovely story

really cute game! love the visuals and the voice acting, everything was really well done
An absolutely beautiful game. Very cute throughout, and had me sobbing at the end.
很喜欢这款游戏!尤其是利用邮票去做各种小任务觉得还蛮有意思的。帮助米拉找信的时候我猜了好多种剧情可能性,但是结局依然出乎意料,直接看哭了TAT,故事写得好好!
感人肺腑的奇幻冒险童话,谢谢你们创作了这么棒的作品。
absolutely ADORE this game. it's so sweet and heartwarming and adorable, and the world building is [i]fantastic[/i]. would absolutely love more games in this world :]
I cried. It's good. The story is simple and clean, the worldbuilding is awesome and is thorougly explained in the "extras" section. The achievements are fun to get, and the voice-acting is AMAZING. The character designs are cute and amazing in their own way, not a single one feels bland or boring, even the ones of background characters. The puzzles are pretty neat too, not too hard and not too easy. However, the game has it's flaws, like sprites of certain characters not being able to properly fit into the frame and their backgrounds just being...completely white. Also certain lines are much, much louder than the others, and the game is really quiet so that can startle some people. overall a great game.
For a short game, this story is full of lovable characters, adorable puzzles, and a heartfelt message about the importance of community, love, and doing one's best for the sake of what's important rather than what the rules say. The voice actors gave their all to the performances and the music choices made for a gorgeous and mysterious ambience. I'm genuinely excited to play their DLC and spend more time in the world. Incredible job!
Such a short, cute story that's definitely worth experiencing. The art is absolutely wonderful, the fantasy setting is really cool, and as a bonus, all the dialogue is voice acted! I really liked the little puzzle segments, though the game is definitely mostly a visual novel, so be aware of that when you get into it! Also, yes I cried at the end. Who wouldn't?
