Katsi Worlds

The katsis have crash-landed on a wild alien planet — 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.
