Bad North: Jotunn Edition

Bad North is a charming yet brutal real-time tactical roguelite. You defend your island kingdom from waves of Viking invaders. The gameplay is simple: you command squads of soldiers, positioning them on the island's terrain to counter incoming threats. The minimalist art style hides a deep, challenging experience where every mistake can lead to the permanent loss of your units.

It is perfect for mobile because the levels are small and self-contained, making it easy to play in short bursts. It is a beautiful, tense, and highly rewarding strategy game that feels great on a touchscreen.
