About this game

The katsis have crash-landed on a wild alien planet β€” help them terraform it, one cozy world at a time!

Lead a squad of adorable katsis as they blast through forests, deserts, crystal caves and glowing bogs. Every tree cleared and rock crushed is harvested into resources. No grinding required: your katsis keep working even while you're away.

🐾 COLLECT 49 KATSIS
Knights, wizards, divers, robots β€” every katsi has a signature ability. Swap your leader to swap your whole playstyle.

βš”οΈ MERGE MIGHTY WEAPONS
Recruit swords, wands, guns, bolts and orbs, then merge matching tiers into ever-stronger gear β€” all the way to the legendary Prisma.

🌱 PRESTIGE & TERRAFORM
Relaunch your expedition to bank Donuts and grow the Terraform tree β€” permanent power that makes every new run faster and deeper.

πŸŒ‹ SIDE EXPEDITIONS
Dig the Deep Shaft for prisms, battle waves in Sprout Defense, face colossal Boss Raids with rival crews, and tame the wilds in Challenge mode β€” where every victory makes the wildlife fiercer.

πŸ† CLIMB THE LEADERBOARDS
Compete worldwide on damage, stage depth and raid streaks. Sign in to keep your save safe in the cloud across devices.

😴 TRUE IDLE PROGRESS
Come back to a stockpile of blooms and a welcome-back bonus. Short sessions, long adventures.
Blast through cozy worlds with a squad of katsis. Merge, tame, prestige!
