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.

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 update on Steam ↗Five of the head accessories have been reshaped. - Apple: thicker stem, plus two new leaves modelled on real apple leaves - Cloud: fuller overall, with the back of the head filled in; new blink - Cat: larger and rounder, eyes sitting properly on the face, rounder tail - Strawberry: bigger, with leaves rebuilt to match real strawberry leaves - Pumpkin: stood upright and taller, stem now properly joined to both the pumpkin and the leaves Mumu keeps all of these on top of the head through every animation, exactly as before.
Read full update on Steam ↗Mumu can now speak even when you're offline. About 1,100 common replies for each of English, Japanese, and Chinese are now built in, so Mumu no longer goes silent without an internet connection.
Read full update on Steam ↗v1.1.26 ✦ Mumu blinks 👁 His eyes now close and open on their own gentle rhythm. All 7 skins have matching closed-eye artwork, so a blink never flashes the wrong colour. Refined look ✨ Skin artwork was repainted — cleaner edges. Lighter 🪶 Some development leftovers were swept out of the build.
Read full update on Steam ↗v1.1.25 ✦ Fixed Fullscreen game conflicts 🎮 —— Thanks to a player report: with the pet running, fullscreen games could get repeatedly kicked out of fullscreen and the whole desktop would flicker. It now recognizes true exclusive fullscreen — windowed and borderless games, and games on other monitors, get the usual company; it only steps aside while an exclusive-fullscreen game owns that screen, then pops back to the front the moment you exit.
Read full update on Steam ↗v1.1.24 ✦ New Move Between Screens 🖥 — For multi-monitor setups, there's a new toggle in the tray. On by default, so Mumu can wander across all your screens. Turn it off and he stays on this one — even dragging won't take him off it. The garden says hello — The calico cat, the cloud, the piglet, the little rabbit, the red panda, the forest shop and the Tree of Life will pop up a small bubble the first time you meet them, telling you what they do. ✦ Play guide rewritten Every interaction is spelled out: long press, scroll to spin him 360°, double-click to pick him up, drag to throw him Garden companions are better explained — for instance, right-click a planted plant to remove it and get half your star dust back Added a performance tip: the star river is fairly heavy, so turn it off from the tray while gaming or watching video ✦ Say What You Think Got an idea? Speak up, don't be shy —...
Read full update on Steam ↗New: press Ctrl+Alt+M to open the chat window directly. No more reaching for the system tray icon. Before, every chat meant moving the mouse down to the bottom edge of the screen, which dragged an auto-hidden taskbar into view (and into screen recordings). Now the keyboard brings it up and the taskbar stays hidden. The hotkey only opens the window — it does not close it. Use the window's own X to close. This is deliberate: RegisterHotKey captures the combination globally, even while you are typing, so a toggle would swallow a half-written message. If another application already owns Ctrl+Alt+M, the hotkey disables itself and the hint is hidden from the tray menu rather than shown as a dead entry.
Read full update on Steam ↗New Re-center 🎯 — a rescue item in the tray menu. If a second monitor or the fullscreen size pushes Mumu off-screen, one click brings them back to the center of your main display. Fixed Window Size 📐 radio not refreshing — the dot in the menu now follows your selection correctly. Window size clamping — width is limited to 960–3000 and forced even, so extreme resolutions no longer misplace the window. Chat / voice rewards now actually credit stardust — reward writes were split into individual files, so several rewards arriving at once no longer overwrite each other. In earlier builds these rewards were lost. Screen-awareness antivirus false positive — no longer shells out to powershell; uses system APIs instead. Also fixed a launcher misdetection. Tweaked Slower water and fishing pacing — fish, bubbles and light shafts all drift more gently, and the bite wait is longer. No rush. Than...
Read full update on Steam ↗This update fixes two issues: • Fixed background process creation that could trigger false positives in some antivirus software • Fixed Mumu incorrectly detecting "gaming" while browsing the Steam / Epic store
Read full update on Steam ↗✦ New 7 color skins: Original / Pharaoh Gold / Cloud Azure / Pale Lavender / Sage Green / Pumpkin Orange / Sakura Blush Right-click the tray icon → Recolor 🎨 All 6 head accessories now blink — each has its own eyelids and its own gaze Tray now supports Chinese / Japanese / English 🌐 ✦ A Small Tip When you're idling or gaming, you can turn the starfield off from the tray with Star River 🌌 — the stars actually stop, not just hide. ✦ Say What You Think Got an idea? Speak up, don't be shy — I'll be bold and keep creating.
