Free kicks and penalties. Real ball flight. Adjustable keeper.
The ball flight here is a real aerodynamic model — gravity, speed-dependent drag, and the Magnus effect, with coefficients from the sports-physics literature. The keeper is a simple visuomotor model: a reaction latency, a read probability, and a reach envelope, all yours to adjust. Hit it dead center at full power and you'll find the knuckleball.

Astro island · React + three.js (react-three-fiber) · hand-written semi-implicit Euler integrator at 120 Hz with drag-crisis Cd and a saturating Magnus lift fit · Mixamo clips converted to a single GLB per character · no backend, no accounts.
