  "description_en": "Reimplements the game server for the Sonic Runners mobile game as a Go service, so Android and iOS clients redirected to it can log in, play Timed and Story modes and use the shop, roulettes, character and Chao progression, events, notices and basic rankings. The README says it was reverse engineered from the Sonic Runners Revival server, on whose code it bases much of its own; it serves about 40 HTTP endpoints of the client's API, decrypts and encrypts AES-CBC request payloads and keeps player state in a bbolt database.",
  "description_zh": "以 Go 服务重新实现手游 Sonic Runners 的游戏服务器，使改为连接它的 Android 和 iOS 客户端能够登录、游玩计时模式和故事模式，并使用商店、轮盘、角色与 Chao 养成、活动、公告和基础排行榜。README 称它是从 Sonic Runners Revival 服务器逆向而来，自身大量代码也以该服务器为基础；它提供客户端 API 的约 40 个 HTTP 端点，对 AES-CBC 请求载荷进行解密和加密，并用 bbolt 数据库保存玩家状态。",
