Tidewell

A cozy true-3D aquarium you build, tend and just sit and watch. Stock a living tank with procedural fish, jellyfish, crabs and shrimp; keep the water sweet; decorate; draw paying visitors; breed rare colour morphs; fill your illustrated journal; and frame a photo of your tank to share. Calm and forgiving — deaths are impossible and offline time is a gift. Cloud-saved progress, bilingual EN/中文, mobile-first. Long-press a fish to name it; tap Watch for a pure ambient view.

Capy Springs

A hot-spring keeper sim with one original verb: CARVE. The mountain spring gushes at 68° and water cools every tile it travels — so the layout of your channels IS the puzzle. Carve ditches down the snowy mountainside, cascade one pool's outflow into the next (capybaras love 42°, snow monkeys 38°, the fox wants a private 35°), mix in the icy stream for precision, roof your pools against winter, and light lanterns for the night crowd. Seasons re-tune the whole network, festival days rank your takings worldwide, and legends — a kappa, an egret sage, a dragon demanding exactly 50.0° — visit the keepers who master the degree. True-3D woodblock-print art, zero bloom. One finger.

MiniTown

Draw tiny blocks of homes, shops, and workplaces, then watch a living town build itself around them. Roads wrap each shared block automatically; buildings rise through visible construction stages; named residents find homes, jobs, favorite shops, routines, walking routes, and little cars. Explore freely, inspect any building or neighbor, and watch cool evenings fill with warm windows and streetlights. A pressure-free low-poly city simulation built for observation, not spreadsheets.

Ledger

You are the town blacksmith — and you never leave the counter. By day, adventurers push open your door: the proud shieldmaiden, the broke rookie begging his first sword on credit, the reckless axeman nobody can talk out of anything. You forge, haggle, extend credit, and decide who gets the last flame-ward charm when two people need it. By night, a paper-puppet theater plays out what your choices bought — when a shield you hammered turns a killing blow, the caption names YOUR work and cites the transaction. At dawn the ledger opens: loot, rumors, repayments… and sometimes a name struck through in wax-red ink, with a death report that quotes your own books. No random deaths — every loss traces to a decision you signed. 36 days, 14 permadeath regulars, six dungeon depths, a legendary blade, five endings — including one where every chair is still full. Hand-inked paper diorama. English & 中文. One thumb.
