Efectazo - a 3D free-kick football game in three.js r160 (Magnus curl, floodlight shadows, procedural grass)

[nightlitdev]

Hi all, I'm a solo dev and I made Efectazo, a free free-kick football game that runs in the browser (HTML5): https://efectazo.pages.dev

 

Tech bits:

- three.js r160, MeshStandardMaterial/PBR, ACES tone mapping

- Night stadium lit by shadow-mapped floodlights

- Procedural grass shader (stripes + noise) instead of textures

- Ball flight integrates gravity, drag and a Magnus force (k·ω×v) each step, so the swipe's sideways component becomes curl

- Keeper AI that reads the shot and dives, plus a defensive wall

- Slow-mo replay of goals, works on phones and desktop

 

Game side: 40 levels, a daily challenge, arcade and cups, English/Spanish. It's free (optional one-time Pro).

 

Would love feedback on performance on your device and on how the curl feels. Happy to share how any part is done.
