Simple Tower - Idle Defense

Simple Tower is a roguelike tower defense game with idle progression and incremental upgrades. Control a single tower and survive endless waves of enemies while building powerful synergies through cards, upgrades, and permanent progression.

Each run challenges you to adapt your strategy. Choose upgrades carefully, combine effects, and push your tower further with every attempt. When your tower falls, you keep your permanent progress and come back stronger.

Build different strategies each run, unlock new upgrade paths, and refine your approach as difficulty increases over time.
