One Button Defense

One Button Defense is a survival game where you must protect a character positioned in the center by using a rotating weapon to defeat incoming enemies.

The character remains stationary, while a sword, or similar weapon, spins continuously around them. By pressing the spacebar or clicking the mouse, you can reverse the direction of the weapon’s rotation, allowing you to time your strikes against approaching foes.

Defeating enemies grants you experience points, a score, and various items.

Upon leveling up, you can choose one of three upgrades, such as increasing rotation speed, extending the weapon's reach, or boosting your maximum health.

As the waves progress, enemies become stronger; the game ends when your health reaches zero.

Your goal is to survive as long as possible, reaching higher waves and achieving the highest score you can.
