NAN NAN PLAYS ALONG
Meet Nan Nan, your little mahjong companion, from your first session. It listens as you clear tiles, reacts to mistakes, comforts your recovery and celebrates your music. Between notes, it looks around and waves from its own little stage.
GROW TOGETHER THROUGH MUSIC
Playing and shared experiences earn resonance across five distinct ages, from newborn to elder. Visit the room for a gentle touch, rest or listening to a performance you have completed. Revisit shared memories and sit together in garden places you have restored. Absence does not erase growth.
CHOOSE YOUR COMPANIONSHIP
Growth, care and immediate reactions work locally. Online pet personalization has its own optional choice. If allowed, AI uses only age, energy and recent performance aggregates to select a contextual emotional response. It receives no pet name, audio or raw input sequence. Turn it off anytime; local companionship continues when the network is unavailable.
Mahjong meets piano in a bright little garden. Match uncovered tiles to the piano keys, and every successful clear plays the next note of an original melody.
ONE TILE. ONE PIANO NOTE.
Ivory tiles are ready to clear. Blue-gray tiles with lock marks are covered; clear the tiles above them first. Look for a tile with nothing covering it, then press the key with the same symbol. Uncover the next layer, hear the next note, and finish your passage. This is a single-player tile-matching puzzle, not traditional four-player mahjong.
A COLORFUL GARDEN, FULL OF FRIENDS
Meet the ferryman, copyist, lamplighter and other garden companions. Read their letters, complete musical passages, collect meaningful keepsakes and revisit places you have restored. Rounded ivory tiles, cheerful characters and a vivid toy-like world make every visit feel welcoming.
PLAY AT YOUR OWN PACE
There is no timer or beat deadline. Choose standard play with three mistake opportunities, or relaxed practice with unlimited mistakes. Both can advance the journey. Optional goals invite you to observe carefully without requiring speed.
CHOOSE A CLEVER ROUTE
Explore fixed-board studies alongside the story. Read the layers, compare shared covers and choose which targets to uncover. Study results stay separate from the chapter memories you have earned. Retrying or resuming keeps the same assigned board.
LISTEN TO WHAT YOU PLAYED
Your in-game key presses become a piano performance. Listen to available reference passages, replay your own recordings and revisit a favorite segment. Your timing is preserved; no microphone recording is needed. Performance ratings are optional and never determine whether you may clear a normal story level.
LOCAL PROGRESS, OFFLINE PLAY
The installed app includes the game, artwork, scores and piano samples. No account is required, and you can play without an Internet connection. Progress, settings and full performances stay on your device. Export a backup of performances you want to keep; uninstalling or clearing app data can remove local saves.
With your permission, automatic difficulty recommendations use a limited summary of recent attempts to help shape future new boards. If the service is unavailable, local rules keep the game playable. Recommendations do not rewrite a board you have already started.
Choose an English or Chinese interface, adjust sound and haptic feedback where supported, and enable reduced motion. Find a bright tile, play its matching key, and let your next melody begin.
On iPad, a wider instrument and companion journey controls make more room for observation and play.
