Play E Loop Não Funcionam

Olá! estou testando o código feito, mas acontece o erro: Uncaught TypeError: Cannot read property 'loop' of undefined (sketch: line 39)

Já vi outras postagens, mas nada deu certo. Meu Código: (As variáveis estão em inglês, só para avisar)

let RacketPosX = 5;
let RacketPosY = 150;

let Collided = false;

//Enemy
let EnemyRacketPosX = 585;
let EnemyRacketPosY = 150;
let EnemyCollided = false;
let EnemyVelocityY;

//Score
let PlayerScore = 0;
let EnemyScore = 0;

//Sounds
let RacketSound;
let ScoreSound;
