Usage:
  game-sdk publish --game-id <id> --name <name> --bundle <file> [--description <text>] [--controls <text>]
  game-sdk asset --game-id <id> --file <file> [--name <filename>]
  game-sdk delete --game-id <id>

Config lookup order:
  1. CLI flags
  2. ./game-sdk.config.json
  3. ./game.config.json
  4. package.json#gameSdk

Examples:
  game-sdk publish --game-id reaction-click --name "反应力挑战" --bundle ./bundle.js --description "快速点击目标拿分" --controls "鼠标点击"
  game-sdk asset --game-id reaction-click --file ./player.png
  game-sdk delete --game-id reaction-click
