CATTO踩踩樹

Pixel idle and animal collecting

One more branch. Who moves in next?

A cat named Catto kneads a little sprout and it grows a bit taller. Every stretch of height brings new animals to move in, and the tree climbs through the canopy, the clouds, the aurora and the stars, all the way to the moon.

Gameplay

Who came today

The numbers are a means; new neighbours are the reward. The field guide holds 50 animals waiting to move in.

All the way to the moon

The finish line is the real Earth to Moon distance, 384,400 km, where the moon rabbit is pounding mochi.

Nothing goes wrong while you're away

The one hard rule of the design: nothing gets worse because you were away.

Day, night and weather

Four times of day, weather, rainbows and fireflies, with music that changes with the hour. Plus 90 achievements.

Under the hood

The rules live in a standalone pure-logic module shared by the tests and a pacing bot, so the idle pacing is measured.

Rendered with PixiJS, designed for portrait phones first and playable on desktop.
