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! 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. 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.
