If there is a programmed connection to the physics for the in-game commentary then it should be here: https://github.com/pncnmnp/xpong/blob/main/main.py#L212

  "- **Shot Angles:** Derive each shot's angle from the (vx, vy) vector:\n"
  "    • Steep angles (>45°) become daring corner lobs or sharp cross-courts.\n"
  "    • Moderate angles (15°-45°) look like graceful arcs that test court coverage.\n"
  "    • Shallow angles (<15°) play out as direct, flat drives down the line.\n"

Didn't find where the balls motion is communicated to the LLM.
