Zero Stress King - Idle Defense(Full Paid) This is a port of the PC game. No ads, no in-app payments, no online required.

A short relaxing incremental game disguised as a tower defense, but enemies can’t reach your walls. Thanks to lava.
Enemies constantly run toward your walls. You buy defenders, upgrade production, and watch the waves grow.
But they can’t reach you. There is a river of lava at the end. Every enemy falls into it. Every time.
This is a tower defense where you already won. Sit back, relax, and enjoy the lava.
