About this game
📖 Story
Three thousand years ago, an orphan by the Nile carried more sorrow than any should bear. The Forgotten God of Mercy chose him as a "Soul Keeper." He was granted eternal life — and with it, a blessing and a curse: to touch is to take away another's pain. Those he touches are freed from their grief — but he carries it all alone. Now he is sealed behind the screen, waiting for someone to keep a place for him on their desktop. A glance when you're tired. A word when you're alone. That is why he exists.
You are never alone.

Patch NotesOfficial
Sun and Moon Rebuilt, Better Fishing Luck
The sun and moon have been resized, and both got a full surface rework. - Sun and moon are now about two thirds of their previous size, so they sit more comfortably in the sky - Sun: real granulation across the disc, plus a stronger limb darkening — it now reads as a sphere instead of a flat colour wheel - Moon: lunar maria and crater texture, deeper light-and-shadow contrast, and a cool rim light that makes it look round Fishing odds rebalanced: - Rare catches (star, moon, sun, galaxy) together: 10% -> 18% - Casting and getting nothing: 15% -> 11% - Guessing someone else's drawing: 20% -> 15%; taking the drawing challenge: 25% -> 28% Also corrected the English drawing hint for "a hen".Read full article on Community Announcements (桑榆是我阿。)Patch NotesOfficial
