  "description_en": "Subway Runner 3D is a procedural Three.js endless runner modeled on Subway Surfers movement and presentation. The author reports using REA and frame-by-frame observation of the original to derive speed, acceleration, jump and gravity values, then implementing lane movement, obstacles and power-ups for browsers and an Android WebView build.",
  "description_zh": "Subway Runner 3D 是以 Subway Surfers 的运动与画面为参照、用 Three.js 制作的程序化无尽跑酷游戏。作者报告借助 REA 和逐帧观察得到速度、加速度、跳跃与重力参数，再实现车道移动、障碍和道具，并提供浏览器及 Android WebView 版本。",
