Developing practical solutions based on this demand…

Pain Points (Public)

Live stream broadcasters and agencies want gamified 9:16 interactive overlays—such as real-time competitive football mechanics—to boost audience retention and virtual gifting, but traditional game engines are too heavy to run cleanly as browser source overlays inside streaming software like OBS.

Suggested Approach (Public)

Build a responsive, lightweight 3D sports mechanics prototype in JavaScript and Three.js optimized for 9:16 vertical canvases, featuring physics-driven gameplay and event hooks designed for seamless integration with live chat and gift webhook triggers.
