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.
Whether you're chasing high scores, experimenting with crazy mods, or just enjoying the chaos, One Button Defense delivers quick, intense fun you can jump into anytime.
