Jev becomes the mind of each fighter in a browser robot fighting game

Built overnight with Opus 5.5, the browser fighting game has Jev read the fight several times a second and choose jabs, low kicks, circling, or clinches, with live odds on screen and bodies driven by MuJoCo physics.

I can't stop making things. Overnight I had Opus 5.5 build a robot fighting game where Jev (@typesafeai) is the mind of each fighter. Jev reads the fight and picks every move a few times a second. Jab, low kick, circle, clinch. Its live odds are on screen the whole time. The bodies are pure physics. MuJoCo running in the browser, real motor torque limits, joints that wear out, and heads that only come off with a clean, hard shot. Next: motion capture from real fighters, tornado kicks and kip-ups.
