One Button Defense is a minimalist yet highly addictive defense game where your only control is switching the rotation of your weapon – clockwise or counterclockwise. Simple Controls, Infinite Challenge – Just one button to reverse your weapon's rotation, but the enemies never stop coming. Explosive Visual Effects – Minimal shapes, maximum particle effects for a satisfying dopamine rush. Endless Difficulty Scaling – Survive as long as you can while the challenge ramps up without limit. Score & Survival Records – Compete with yourself or friends for the highest score. Built-in Modding Support – Add JS files to the mods/ folder or code directly in the in-game mod editor. Create new weapons, change enemy behavior, or break the rules entirely.
