    • Starts the Spawner

    • Set the Spawner's activeSpawning = true

    • Calls Spawner's StartSpawning( ) method.

  • if MiniGameState.active

    • Check that Health is still greater than 0

    • If Health is Greater than 0

      • Check Score, if Score > WinScore

        • Set MiniGameState.Win

        • Call GameOver( )
